To determine the driving forces for symplastic sugar flux between mesophyll and phloem, gradients of sugar concentrations and osmotic pressure were studied in leaf tissues of two Scrophulariaceae species, Alonsoa meridionalis and Asarina barclaiana. A. meridionalis has a typical symplastic configuration of minor-vein phloem, i.e. intermediary companion cells with highly developed plasmodesmal connections to bundle-sheath cells. In A. barclaiana, two types of companion cells, modified intermediary cells and transfer cells, were found in minor-vein phloem, giving this species the potential to have a complex phloem-loading mode. We identified all phloem-transported carbohydrates in both species and analyzed the levels of carbohydrates in chloroplasts, vacuoles, and cytoplasm of mesophyll cells by nonaqueous fractionation. Osmotic pressure was measured in single epidermal and mesophyll cells and in whole leaves and compared with calculated values for phloem sap. In A. meridionalis, a 2-fold concentration gradient for sucrose between mesophyll and phloem was found. In A. barclaiana, the major transported carbohydrates, sucrose and antirrhinoside, were present in the phloem in 22- and 6-fold higher concentrations, respectively, than in the cytoplasm of mesophyll cells. The data show that diffusion of sugars along their concentration gradients is unlikely to be the major mechanism for symplastic phloem loading if this were to occur in these species. We conclude that in both A. meridionalis and A. barclaiana, apoplastic phloem loading is an indispensable mechanism and that symplastic entrance of solutes into the phloem may occur by mass flow. The conditions favoring symplastic mass flow into the phloem are discussed.

The floral oils of Diascia purpurea, Diascia vigilis, Diascia cordata, Diascia megathura, Diascia integerrima and Diascia barberae (Scrophulariaceae) were selectively collected from trichome elaiophores. The derivatized floral oils were analyzed by gas chromatography-mass spectrometry (GC-MS), whilst the underivatized samples were analysed by electrospray ionization mass spectrometry (ESI-MS) and Fourier-transform ion cyclotron resonance mass spectrometry (FTICR-MS). The most common constituents of the floral oils investigated are partially acetylated acylglycerols of (3R)-acetoxy fatty acids (C(14), C(16), and C(18)), as was proven with non-racemic synthetic reference samples. The importance of these oils for Rediviva bees is discussed in a co-evolutionary context.

Knop, C; Voitsekhovskaja, O; Lohaus, G

2001-05-01

In order to study differences between sugar transport in oligosaccharide-translocating and sucrose-translocating species, two members of the Scrophulariaceae, Asarina barclaiana Pennell and Alonsoa meridionalis O. Kuntze, were analysed regarding minor-vein anatomy, sugar concentrations in leaves and phloem sap, and expression of sucrose transporters. The minor veins of Asarina barclaiana possess mainly transfer cells and modified intermediary cells and those of Alonsoa meridionalis have intermediary cells and ordinary companion cells. Phloem sap from these plants was collected by the laser-aphid-stylet technique. The main carbon transport forms in Asarina were sucrose and in Alonsoa raffinose and stachyose. The sum of the carbohydrate concentrations in the phloem sap of both species was as high as that in apoplastic phloem loaders. In Asarina the ratio of the sucrose concentration in the phloem to that in the cytosol of source cells was about 35 and the corresponding ratio in Alonsoa was about two. Sucrose transporter cDNAs were isolated from leaves of both species. By means of semi-quantitative reverse transcription-polymerase chain reaction, sucrose transporter mRNA was detected in different organs and also in the phloem sap. This is the first time that sucrose transporters have been found in oligosaccharide-translocating species and that the mRNA of these sucrose transporters has been localized directly in the phloem sap. Taken together, our observations indicate that Asarina is an apoplastic phloem loader, while the results for Alonsoa are ambiguous: some properties are typical of the symplastic phloem-loading mechanism, but probably a sucrose transporter is involved in loading and/or retrieval of sucrose into the phloem.

Familial placement and relations of Rehmannia and Triaenophora (Scrophulariaceae s.l.) inferred from five gene regions.

Xia, Zhi; Wang, Yin-Zheng; Smith, James F

2009-02-01

Accurate classification systems based on evolution are imperative for biological investigations. The recent explosion of molecular phylogenetics has resulted in a much improved classification of angiosperms. More than five phylogenetic lineages have been recognized from Scrophulariaceae sensu lato since the family was determined to be polyphyletic; however, questions remain about the genera that have not been assigned to one of the segregate families of Scrophulariaceae s.l. Rehmannia Liboschitz and Triaenophora Solereder are such genera with uncertain familial placement. There also is debate whether Triaenophora should be segregated from Rehmannia. To evaluate the phylogenetic relations between Rehmannia and Triaenophora, to find their closest relatives, and to verify their familial placement, we conducted phylogenetic analyses of the sequences of one nuclear DNA (ITS) region and four chloroplast DNA gene regions (trnL-F, rps16, rbcL, and rps2) individually and combined. The analyses showed that Rehmannia and Triaenophora are each strongly supported as monophyletic and together are sister to Orobanchaceae. This relation was corroborated by phytochemical and morphological data. Based on these data, we suggest that Rehmannia and Triaenophora represent the second nonparasitic branch sister to the remainder of Orobanchaceae (including Lindenbergia).

2015-01-01

This is a review on 95 references dealing with the genus Linaria (Scrophularioideae-Antirrhineae tribe), a known genus of the Scrophulariaceae family, which comprises about 200 species mainly distributed in Europe, Asia and North Africa. The use of some Linaria species in folk medicine has attracted the attention for chemical and biological studies. This report is aimed to be a comprehensive overview on the isolated or identified known and often new metabolites from the 41 Linaria species so far cited. It is organised presenting first the phytochemical classes of alkaloids, polyphenols including flavonoids, the latter being quite diffused and mostly present as flavones, flavonols and their glycosides, and terpenoids including iridoids and steroids. Second, the results from biological investigation on plant extracts, pure natural products isolated from Linaria species and some synthetic derivatives are reported, with antitumour, anti-acetylcholinesterase, anti-inflammatory and analgesic, antioxidant and antibacterial activities.

Scrophularia dentata is an important Tibetan medicinal plant and traditionally used for the treatment of exanthema and fever in Traditional Tibetan Medicine (TTM). However, there is little sequence and genomic information available for S. dentata. In this paper, we report the complete chloroplast genome sequence of S. dentata and it is the first sequenced member of the Sect. Tomiophyllum within Scrophularia (Scrophulariaceae). The gene order and organization of the chloroplast genome of S. dentata are similar to other Lamiales chloroplast genomes. The plastome is 152,553 bp in length and includes a pair of inverted repeats (IRs) of 25,523 bp that separate a large single copy (LSC) region of 84,058 bp and a small single copy (SSC) region of 17,449 bp. It has 38.0% GC content and includes 114 unique genes, of which 80 are protein-coding, 30 are transfer RNA, and 4 are ribosomal RNA. Also, it contains 21 forward repeats, 19 palindrome repeats and 41 simple sequence repeats (SSRs). The repeats and SSRs within S. dentata were compared with those of S. takesimensis and present certain discrepancies. The chloroplast genome of S. dentata was compared with other five publicly available Lamiales genomes from different families. All the coding regions and non-coding regions (introns and intergenic spacers) within the six chloroplast genomes have been extracted and analysed. Furthermore, the genome divergent hotspot regions were identified. Our studies could provide basic data for the alpine medicinal species conservation and molecular phylogenetic researches of Scrophulariaceae and Lamiales.

Rehmannia glutinosa (Scrophulariaceae) is used in traditional Chinese medicine. Microsatellite primers were developed and characterized for this species to evaluate its genetic diversity and population genetic structure. Sixteen microsatellite loci were isolated from R. glutinosa using an enriched genomic library, and these markers were characterized in two wild populations of this species. The number of alleles per locus ranged from two to 20. A high genetic diversity was observed in two populations, with average observed heterozygosity of 0.812 and 0.794, and average expected heterozygosity of 0.802 and 0.814, respectively. Rehmannia glutinosa is an important medicinal resource. The genetic markers described in our study will be useful for future population genetic studies and molecular breeding programs on this species.

The mutagenic and antimutagenic activities of triterpene betulinic acid {3b-3-hydroxy-lup-20(29)-en-28-oic} isolated from the roots of Scoparia dulcis (Scrophulariaceae) were analyzed using the somatic mutation and recombination test (SMART) in the wings of Drosophila melanogaster. The mutagenic potential of betulinic acid was evaluated at 3 different concentrations (1.64, 3.28, and 6.57 mM). Antimutagenic activity evaluation was performed by co-treatment trials in which the flies received betulinic acid at 3 different concentrations in addition to 10 mM pro-mutagenic urethane. The results demonstrated that betulinic acid was not capable of causing DNA damage. However, the frequency of small single spots, large spots, and twin spots was significantly reduced. In the high bioactivation cross, betulinic acid was significantly active and exerted enhanced antimutagenic activity, possibly as a desmutagen.

Pollinator attraction of the wasp-flower Scrophularia umbrosa (Scrophulariaceae).

Brodmann, J; Emer, D; Ayasse, M

2012-05-01

Certain species of Scrophularia (Scrophulariaceae), such as S. nodosa and S. umbrosa, are mainly pollinated by social wasps and are consequently described as wasp-flowers. Because plants attract their pollinators with the help of various floral cues, such as floral odour and/or optical cues, we have investigated the role of olfactory and visual floral signals responsible for wasp attraction in S. umbrosa. Using a combination of chemical (GC, GC-MS) and electrophysiological analyses (GC-EAD), we identified ten compounds in the complex floral odour bouquet that are detectable by the wasps' antennae. As in the wasp-flower Epipactis helleborine, we found so-called 'green leaf volatiles' (GLVs) in the floral odour; these GLVs are highly attractive to the wasps. GLVs, mostly six-carbon aldehydes, alcohols and acetates, and other volatile organic compounds (VOCs), are emitted by many plants infested with herbivores, e.g. caterpillars. In contrast to other investigated wasp-flowers, behavioural experiments have demonstrated that, in addition to the floral odour of S. umbrosa, visual cues are involved in pollinator attraction. © 2011 German Botanical Society and The Royal Botanical Society of the Netherlands.

The genus Eremophila (Scrophulariaceae): an ethnobotanical, biological and phytochemical review.

Singab, Abdel Nasser; Youssef, Fadia S; Ashour, Mohamed L; Wink, Michael

2013-09-01

Eremophila (Scrophulariaceae) is an endemic Australian genus with 214 species, which is commonly known as Fuchsia bush, Emu bush or Poverty bush. Plants of this genus played an important role for the Australian Aborigines who used them widely for medicinal and ceremonial purposes. Many studies have been carried out on many species of this genus and have generated immense data about the chemical composition and corresponding biological activity of extracts and isolated secondary metabolites. Thorough phytochemical investigations of different Eremophila species have resulted in the isolation of more than 200 secondary metabolites of different classes with diterpenes as major constituents. Biological studies and traditional clinical practice demonstrated that Eremophila and its bioactive compounds possess various pharmacological properties. Plants were employed especially as a cardiotonic drug and also as potent anti-inflammatory, antimicrobial and antiviral agents. Further investigations are required to explore other Eremophila species, to evaluate the different biological activities of either their extracts or the isolated compounds and the possible underlying modes of action. © 2013 Royal Pharmaceutical Society.

Scoparia dulcis Linn (Scrophulariaceae) together with other medicinal plants serve as antisickling remedies in Africa. This study was aimed at investigating the antisickling activity of the leaves of the plant as well as establishing the toxicological profile. Chemical tests were employed in phytochemical investigations. Evaluation of the antisickling activity involved the inhibition of sodium metabisulphite-induced sickling of the HbSS red blood cells obtained from confirmed sickle cell patients who were not in crises. Concentrations of the crude extract and its fractions were tested with normal saline and p-hydroxybenzoic acid serving as controls. Acute toxicological evaluation was carried out in mice while 30-day assessment was done in rats. Phytochemical screening revealed the presence of alkaloids, tannins, flavonoids and saponins. Percentage sickling inhibitions of the aqueous methanol extracts of S. dulcis were significant all through the period of assay p Scoparia dulcis in the management of Sickle cell disorders and a candidate for further investigations.

C(4) photosynthesis independently evolved >62 times, with the majority of origins within 16 dicot families. One origin occurs in the poorly studied genus Anticharis Endl. (Scrophulariaceae), which consists of ~10 species from arid regions of Africa and southwest Asia. Here, the photosynthetic pathway of 10 Anticharis species and one species from each of the sister genera Aptosimum and Peliostomum was identified using carbon isotope ratios (δ(13)C). The photosynthetic pathway was then mapped onto an internal transcribed spacer (ITS) phylogeny of Anticharis and its sister genera. Leaf anatomy was examined for nine Anticharis species and plants from Aptosimum and Peliostomum. Leaf ultrastructure, gas exchange, and enzyme distributions were assessed in Anticharis glandulosa collected in SE Iran. The results demonstrate that C(3) photosynthesis is the ancestral condition, with C(4) photosynthesis occurring in one clade containing four species. C(4) Anticharis species exhibit the atriplicoid type of C(4) leaf anatomy and the NAD-malic enzyme biochemical subtype. Six Anticharis species had C(3) or C(3)-C(4) δ(13)C values and branched at phylogenetic nodes that were sister to the C(4) clade. The rest of Anticharis species had enlarged bundle sheath cells, close vein spacing, and clusters of chloroplasts along the centripetal (inner) bundle sheath walls. These traits indicate that basal-branching Anticharis species are evolutionary intermediates between the C(3) and C(4) conditions. Anticharis appears to be an important new group in which to study the dynamics of C(4) evolution.

Inversostyly: a new stylar polymorphism in an oil-secreting plant, Hemimeris racemosa (Scrophulariaceae).

A new kind of stylar polymorphism, provisionally called inversostyly, is described. The polymorphism occurs in Hemimeris racemosa (Scrophulariaceae), a common annual herb of the Cape region of South Africa. Most populations are dimorphic for style orientation: the style alternates with the two stamens and is deflected either upwards or downwards. Thus, there is reciprocal placement of the style and stamens in a vertical plane in zygomorphic flowers. The flowers are symmetrical, and the floral parts do not vary in length. All flowers on a given plant are of the same stylar orientation. Pollination is by specialized oil-collecting bees (Rediviva spp.), which carry the pollen of the two morphs separately in discrete anterior or posterior locations on the underside of the body. Most inversostylous populations have a slightly higher proportion of the style-down morph, and this bias increases with decreasing pollinator abundance. In contrast with inversostylous populations, all individuals in homostylous populations of H. racemosa have the style and the stamens clustered together in the down position and high levels of autogamous seed set. Homostylous populations of H. racemosa, as well as the homostylous species Hemimeris sabulosa, occur where oil-collecting bees are less abundant.

Verbascum antiochium Boiss., a member of the Scrophulariaceae family, is endemic to Turkey. The extracts obtained from V. antiochium by increased polarity and direct methanol extraction were tested by the agar well diffusion method against various Gram-positive and Gram-negative bacteria and one fungus. The methanol/water extract exhibited a larger inhibition zone against both the Gram-negative and Gram-positive bacteria than the other extracts. Haemophilus influenzae was found to be the most sensitive bacterium among the bacteria tested. The antioxidant activities of the methanolic extract of V. antiochium were examined by two complementary test systems. The 50% inhibition activity of the methanolic extract of V. antiochium against the free radical 2,2-diphenyl-1-picrylhydrazyl was determined as 4.80 mg/mL. In the case of the linoleic acid system, oxidation of linoleic acid was inhibited by the methanolic extract of V. antiochium with 79.92% inhibition, which is close to the value of the synthetic antioxidant reagent, tert-butylated hydroxytoluene. The total phenolic components of V. antiochium were determined to be 92.71 mg of gallic acid equivalents/g. Iridoid glycosides, flavonoids, and saponins were detected as the major chemical constituents in the extract.

Various extracts of the aerial parts of Barkleyanthus salicifolius (Asteraceae) and Penstemon gentianoides (Scrophulariaceae) have been used in folk medicine to treat many ailments, particularly inflammation and migraine. Neither the bioactive components responsible nor the mechanisms involved have been evaluated. Here are reported antioxidant activities of their methanol, dichloromethane, and ethyl acetate extracts. Samples were evaluated for oxygen radical absorption capacity (ORAC), ferric reducing antioxidant power (FRAP), 2,2-diphenyl-1-picryl-hydrazyl (DPPH) radical scavenging, and inhibition of the formation of thiobarbituric acid reactive species (TBARS), a measure of lipid peroxidation. Antioxidant activities were strongly correlated with total polyphenol content. The most active extracts from P. gentianoides in scavenging DPPH radicals and inhibiting TBARS formation were the methanol extract (A) and a further ethyl acetate extract of this (E). Partition E was further divided into eight fractions, and both E and the fractions were compared for activity against butylated hydroxytoluene, quercetin, and tocopherol. Partition E and the most active fractions, 5 and 6, were found to have I(50) values of 14.1, 38.6, and 41.8 ppm, respectively, against DPPH and 18.5, 26.0, and 12.7 ppm, respectively, against TBARS formation. Consistent with this finding, partition E and fractions 4-6 had the greatest ORAC and FRAP values. These results show that these plants could be useful antioxidant sources.

The genus Zaluzianskya (Scrophulariaceae s.s.) encompasses a diversity of floral and ecological traits. However, this diversity, as described by the current taxonomic circumscription of Zaluzianskya, is an underestimate. We present molecular data suggesting that this genus requires expansion via incorporation of species from other genera and recognition of unnamed cryptic species. This study advances prior molecular phylogenies of the southern African genus through the addition of DNA regions and 51 populations that had not previously been sampled in a published phylogeny. A total of 82 species of Zaluzianskya and related genera are included, adding 48 to those previously sampled. Results are presented from analyses of five DNA regions, including nuclear ITS and four rapidly evolving chloroplast regions (trnL-trnF, rpl16, rps16, and trnS-trnfM). Our primary finding is that the genus Phyllopodium is polyphyletic as currently circumscribed, with some species placed within Zaluzianskya and others grouping with Polycarena, indicating the need for further phylogenetic work on these genera. Preliminary support for the incorporation of Reyemia into Zaluzianskya is reinforced here by the first molecular analysis to include both species of Reyemia and a strong sampling of species across Zaluzianskya and major clades of tribe Limoselleae. The two disjunct, tropical African species of Zaluzianskya are also confirmed as members of this genus. Finally, a broad sampling of 21 populations of Z. microsiphon establishes their phylogenetic division into two to five separate lineages. Hybridization, coevolution, and cryptic speciation may each play a role in the evolution of Z. microsiphon. Further resolution within a clade comprising sections Nycterinia and Macrocalyx is needed to better understand their relationships. Copyright © 2017 Elsevier Inc. All rights reserved.

Full Text Available When parasitic plants and aphid herbivores share a host, both direct and indirect ecological effects (IEEs can influence evolutionary processes. We used a hemiparasitic plant (Rhinanthus minor, a grass host (Hordeum vulgare and a cereal aphid (Sitobion avenae to investigate the genetics of IEEs between the aphid and the parasitic plant, and looked to see how these might affect or be influenced by the genetic diversity of the host plants. Survival of R. minor depended on the parasite’s population of origin, the genotypes of the aphids sharing the host and the genetic diversity in the host plant community. Hence the indirect effects of the aphids on the parasitic plants depended on the genetic environment of the system. Here, we show that genetic variation can be important in determining the outcome of IEEs. Therefore, IEEs have the potential to influence evolutionary processes and the continuity of species interactions over time.

The antiviral activity of five diterpenoids isolated from Scoparia dulcis L., Scrophulariaceae, was examined in vitro against herpes simplex virus type 1. Among these compounds, only scopadulcic acid B was found to inhibit the viral replication with the in vitro therapeutic index of 16.7. The action of scopadulcic acid B was not due to a direct virucidal effect or inhibition of virus attachment to host cells. Single-cycle replication experiments indicated that the compound interfered with considerably early events of virus growth. The influence of scopadulcic acid B on the course of the primary corneal herpes simplex virus infection was investigated by means of a hamster test model. When the treatment was initiated immediately after virus inoculation, scopadulcic acid B, when applied orally or intraperitoneally, effectively prolonged both the appearance of herpetic lesions and the survival time at the dose of 100 and 200 mg/kg per day.

The present study was performed to evaluate the in vitro antimicrobial and antioxidant properties of various extracts of Verbascum (V.) pinetorum, a member of Scrophulariaceae family. While the antimicrobial activity of various extracts of V. pinetorum was determined with agar-well diffusion method, the antioxidant activity was examined with two complementary test systems, namely 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging and beta-carotene/linoleic acid test systems. The hexane extract exhibits antimicrobial activity against few microorganisms. However, dichloromethane, direct methanol and methanol/chloroform extracts are effective on a broad range of microorganisms. Among the tested bacteria Haemophilus influenzae was found to be the most sensitive bacterium. The 50% (IC50) inhibition activity of the methanolic extract of V. pinetorum on the free radical DPPH was determined as 13.04 mg/ml. In the case of the linoleic acid system, oxidation of linoleic acid was inhibited by methanolic extract of V. pinetorum, which showed 89.39% inhibition that is quite close to the value of the synthetic antioxidant reagent butylhydroxytoluene (BHT), 92.46%. Iridoid glycosides, flavonoids and saponins were determined as the major natural compounds in the methanolic extracts. The total phenolic components of V. pinetorum were found as 42.45 mg/g gallic acid equivalent. The results provide evidence that the extracts of V. pinetorum contained iridoid glycosides, flavonoids, saponins and phenolic compounds which may be responsible for the substantial antimicrobial and antioxidant activities.

In this study, we determined the heavy metal content (Cd(2+), Cr(3+), Cu(2+), Fe(3+), Ni(2+), Pb(2+), and Zn(2+)) in the soil surrounding the roots and different organs of Verbascum bombyciferum Boiss. (Scrophulariaceae), which is endemic to Uludağ Mountain, Bursa, Turkey. Plant samples were collected from roadsides, and heavy metal accumulation capabilities were tested. This is one of the pioneer species of ruderal plant communities on roadsides, building sites, rubbish dumps, etc. Different organs of plant samples (roots, stems, leaves, and flowers) and their soils were analyzed by inductively couple plasma optical emission spectroscopy for their heavy metal contents. Some of the analyzed heavy metals (Cd(2+), Cr(3+), Pb(2+), and Zn(2+)) were usually increased depending on the traffic in the sample sites, and this variation was also reflected in heavy metal content of plant samples. Our results show that this plant can be used as a bio-indicator species in the monitoring of increased Cd(2+), Cr(3+), Pb(2+), and Zn(2+) in the environment. We also concluded that V. bombyciferum have the capability of Cd(2+), Cr(3+), Cu(2+), Ni(2+), Pb(2+), and Zn(2+) accumulation.

Full Text Available Agalinis Raf. consists approximately of 60 species, 14 of which occur in Brazil. The genus presents predominantly american distribution and the Brazilian species appears mainly in high areas of Minas Gerais. The North-American species are refered as hemiparasites, but there is no anatomical data about it in relation to the Brazilian species. Anatomical studies were conducted to verify whether the Agalinis species from Brazil were root parasites or not. The eight species analysed were presented haustoria which varied in shape, arrangement and size. They were generally elliptic or globose structures and mostly were tightly sticked to other roots in a solitary or clustered manner. The seriate sections of haustoria showed that there was a xylem connection between them and the roots in which they were attached. This fact has confirmed for the first time the occurrence of parasitism in the Brazilian species of Agalinis.Agalinis Raf.

Corolla herbivory, pollination success and fruit predation in complex flowers: an experimental study with Linaria lilacina (Scrophulariaceae).

Science.gov (United States)

Sánchez-Lafuente, Alfonso M

2007-02-01

Herbivory on floral structures has been postulated to influence the evolution of floral traits in some plant species, and may also be an important factor influencing the occurrence and outcome of subsequent biotic interactions related to floral display. In particular, corolla herbivory may affect structures differentially involved in flower selection by pollinators and fruit predators (specifically, those ovopositing in ovaries prior to fruit development); hence floral herbivores may influence the relationships between these mutualistic and antagonistic agents. The effects of corolla herbivory in Linaria lilacina (Scrophulariaceae), a plant species with complex flowers, were considered in relation to plant interactions with pollinators and fruit predators. Tests were made as to whether experimentally created differences in flower structure (resembling those occurring naturally) may translate into differences in reproductive output in terms of fruit or seed production. Flowers with modified corollas, particularly those with lower lips removed, were less likely to be selected by pollinators than control flowers, and were less likely to be successfully visited and pollinated. As a consequence, fruit production was also less likely in these modified flowers. However, none of the experimental treatments affected the likelihood of visitation by fruit predators. Since floral herbivory may affect pollinator visitation rates and reduce seed production, differences among plants in the proportion of flowers affected by herbivory and in the intensity of the damage inflicted on affected flowers may result in different opportunities for reproduction for plants in different seasons.

Plant terpenoids are a large and highly diverse class of metabolites with an important role in the immune defense. They find wide industrial application as active pharmaceutical ingredients, aroma and fragrance compounds. Several Eremophila sp. derived terpenoids have been documented. To elucidate the terpenoid metabolism, the transcriptome of juvenile and mature Eremophila serrulata (A.DC.) Druce (Scrophulariaceae) leaves was sequenced and a transcript library was generated. We report on the first transcriptomic dataset of an Eremophila plant. IlluminaMiSeq sequencing (2 × 300 bp) revealed 7,093,266 paired reads, which could be assembled to 34,505 isogroups. To enable detection of terpene biosynthetic genes, leaves were separately treated with methyl jasmonate, a well-documented inducer of plant secondary metabolites. In total, 21 putative terpene synthase genes were detected in the transcriptome data. Two terpene synthase isoenzymatic genes, termed ES01 and ES02, were successfully expressed in E. coli. The resulting proteins catalyzed the conversion of geranyl pyrophosphate, the universal substrate of monoterpene synthases to myrcene and Z-(b)-ocimene, respectively. The transcriptomic data and the discovery of the first terpene synthases from Eremophila serrulata are the initial step for the understanding of the terpene metabolism in this medicinally important plant genus.

1991-01-01

The concept of minor actinide burner reactor is proposed as an efficient way to transmute long-lived minor actinides in order to ease the burden of high-level radioactive waste disposal problem. Conceptual design study of minor actinide burner reactors was performed to obtain a reactor model with very hard neutron spectrum and very high neutron flux in which minor actinides can be fissioned efficiently. Two models of burner reactors were obtained, one with metal fuel core and the other with particle fuel core. Minor actinide transmutation by the actinide burner reactors is compared with that by power reactors from both the reactor physics and fuel cycle facilities view point. (author)

Minority stress theory has widespread research support in explaining health disparities experienced by sexual and gender minorities. However, less is known about how minority stress impacts multiply marginalized groups, such as lesbian, gay, bisexual, and transgender people of color (LGBT POC). Also, although research has documented resilience in the face of minority stress at the individual level, research is needed that examines macro-level processes such as community resilience (Meyer, 2015). In the current study, we integrate minority stress theory and intersectionality theory to examine multiple minority stress (i.e., racial/ethnic stigma in LGBT spaces and LGBT stigma in one's neighborhood) and community resilience (i.e., connection to LGBT community) among sexual minority men of different racial/ethnic groups who use a geosocial networking application for meeting sexual partners. Results showed that Black sexual minority men reported the highest levels of racial/ethnic stigma in LGBT spaces and White sexual minority men reported the lowest levels, with Asian and Hispanic/Latino men falling in between. Consistent with minority stress theory, racial/ethnic stigma in LGBT spaces and LGBT stigma in one's neighborhood were associated with greater stress for sexual minority men of all racial/ethnic groups. However, connection to LGBT community played more central role in mediating the relationship between stigma and stress for White than POC sexual minority men. Results suggest that minority stress and community resilience processes may differ for White and POC sexual minority men. Potential processes driving these differences and implications for minority stress theory are discussed.

A new genus and twenty new species of Australian jumping plant-lice (Psylloidea: Triozidae) from Eremophila and Myoporum (Scrophulariaceae: Myoporeae).

The Triozidae is a diverse, cosmopolitan family of jumping plant-lice (Hemiptera: Psylloidea) from an exceptionally diverse range of plant families, but with few described Australian species. As a direct outcome of the Australian Biological Resources Study Bush Blitz species discovery program, many new Psylloidea from novel host plants in remote localities have been revealed. In this study a new genus Myotrioza Taylor gen. nov. and 20 new species are described from southern and central Australia which also establishes the first host plant records from Eremophila and Myoporum (Scrophulariaceae: Myoporeae). New species, delineated using a combination of morphological and mitochondrial COI sequence data, are: Myotrioza clementsiana sp. nov., M. darwinensis sp. nov., M. desertorum sp. nov., M. eremi sp. nov., M. eremophili sp. nov., M. flindersiana sp.nov., M. gawlerensis sp. nov., M. insularis sp. nov., M. interioris sp. nov., M. interstantis sp. nov., M. longifoliae sp. nov., M. markmitchelli sp. nov., M. myopori sp. nov., M. oppositifoliae sp. nov., M. pantonii sp. nov., M. platycarpi sp. nov., M. remota sp. nov., M. scopariae sp. nov., M. serrulatae sp. nov., and M. telowiensis sp. nov. Genetic divergence data, host associations, biogeographic data, diagnoses and a key to species are presented. Myotrioza appears to be particularly diverse in ephemeral southern Australia, especially in inland Western Australia and South Australia, matching regions of high diversity of the host genera; some species are likely to be short range endemics.

Chemical and mechanical defenses vary among maternal lines and leaf ages in Verbascum thapsus L. (Scrophulariaceae and reduce palatability to a generalist insect.

Directory of Open Access Journals (Sweden)

Full Text Available Intra-specific variation in host-plant quality affects herbivore foraging decisions and, in turn, herbivore foraging decisions mediate plant fitness. In particular, variation in defenses against herbivores, both among and within plants, shapes herbivore behavior. If variation in defenses is genetically based, it can respond to natural selection by herbivores. We quantified intra-specific variation in iridoid glycosides, trichome length, and leaf strength in common mullein (Verbascum thapsus L, Scrophulariaceae among maternal lines within a population and among leaves within plants, and related this variation to feeding preferences of a generalist herbivore, Trichopulsia ni Hübner. We found significant variation in all three defenses among maternal lines, with T. ni preferring plants with lower investment in chemical, but not mechanical, defense. Within plants, old leaves had lower levels of all defenses than young leaves, and were strongly preferred by T. ni. Caterpillars also preferred leaves with trichomes removed to leaves with trichomes intact. Differences among maternal lines indicate that phenotypic variation in defenses likely has a genetic basis. Furthermore, these results reveal that the feeding behaviors of T. ni map onto variation in plant defense in a predictable way. This work highlights the importance of variation in host-plant quality in driving interactions between plants and their herbivores.

Intra-specific variation in host-plant quality affects herbivore foraging decisions and, in turn, herbivore foraging decisions mediate plant fitness. In particular, variation in defenses against herbivores, both among and within plants, shapes herbivore behavior. If variation in defenses is genetically based, it can respond to natural selection by herbivores. We quantified intra-specific variation in iridoid glycosides, trichome length, and leaf strength in common mullein (Verbascum thapsus L, Scrophulariaceae) among maternal lines within a population and among leaves within plants, and related this variation to feeding preferences of a generalist herbivore, Trichopulsia ni Hübner. We found significant variation in all three defenses among maternal lines, with T. ni preferring plants with lower investment in chemical, but not mechanical, defense. Within plants, old leaves had lower levels of all defenses than young leaves, and were strongly preferred by T. ni. Caterpillars also preferred leaves with trichomes removed to leaves with trichomes intact. Differences among maternal lines indicate that phenotypic variation in defenses likely has a genetic basis. Furthermore, these results reveal that the feeding behaviors of T. ni map onto variation in plant defense in a predictable way.

While much attention has been directed at improving the quality of care at the end of life, few studies have examined what determines a good death in different individuals. We sought to identify common domains that characterize a good death in a diverse range of community-dwelling individuals, and to describe differences that might exist between minority and non-minority community-dwelling individuals' views. Using data from 13 focus groups, we identified 10 domains that characterize the quality of the death experience: 1) physical comfort, 2) burdens on family, 3) location and environment, 4) presence of others, 5) concerns regarding prolongation of life, 6) communication, 7) completion and emotional health, 8) spiritual care, 9) cultural concerns, 10) individualization. Differences in minority compared to non-minority views were apparent within the domains of spiritual concerns, cultural concerns, and individualization. The findings may help in efforts to encourage more culturally sensitive and humane end-of-life care for both minority and non-minority individuals.

Limosella is a small aquatic genus of Scrophulariaceae of twelve species, of which one is distributed in northern circumpolar regions, two in southern circumpolar regions, two in the Americas, one endemic to Australia, and six in tropical or southern Africa or both. The Australasian L. curdieana has always been considered distinct but its close phylogenetic relationships have never been inferred. Here, we investigated the following alternative phylogenetic hypotheses based on comparative leaf morphology and habitat preferences or floral morphology: (1) L. curdieana is sister to the African L. grandiflora; or (2) it is closely related to a group of other African species and the northern circumpolar L. aquatica. We tested these hypotheses in a phylogenetic framework using DNA sequence data from four plastid DNA regions and the nuclear ITS region. These were analyzed using maximum parsimony and Bayesian inference. We obtained moderately resolved, partially conflicting phylogenies, supporting that accessions of L. grandiflora form the sister group to the rest of the genus and that L. curdieana groups with the African taxa, L. africana and L. major, and L. aquatica. Thus, the molecular evidence supports the second hypothesis. A biogeographic analysis suggests an out-of-southern Africa scenario and several dispersal events in the Southern Hemisphere. Past dispersal from southern Africa to Australasia is suggested, yet it cannot be excluded that a route via tropical Africa and temperate Asia has existed.

A protocol for de novo regeneration and rapid micropropagation of Scrophularia yoshimurae (Scrophulariaceae) has been developed. Multiple shoot development was achieved by culturing the shoot-tip, leaf-base, stem-node and stem-internode explants on Murashige and Skoog (MS) medium supplemented with 4.44 microM N6-benzyladenine (BA) and 1.07 microM alpha-naphthaleneacetic acid (NAA). Stem-node and shoot-tip explants showed the highest response (100%) followed by stem-internode (74.4%) and leaf-base (7.7%) explants. The shoots were multiplied by subculturing on the same medium used for shoot induction. Shoots were rooted on growth regulator-free MS basal medium and the plantlets were transplanted to soil and acclimatized in the growth chamber. The content of harpagoside, a quantitatively predominant iridoid glycoside, in different plant material was determined by high performance liquid chromatography (HPLC). The analysis revealed that the content of harpagoside in the aerial and underground parts of S. yoshimurae was significantly higher than the marketed crude drug (underground parts of Scrophularia ningpoensis).

There are (March, 1988) 3774 minor planets which have received a permanent number. Of these, there are some whose mean distance to the sun is very nearly equal to that of Jupiter, and whose heliocentric longitudes from that planet are about 60°, so that the three bodies concerned (sun, Jupiter, minor planet) make an approximate equilateral triangle. These minor planets, which occur in two distinct groups, one preceding Jupiter and one following, have received the names of the heroes of the Trojan war. This paper concerns the 49 numbered minor planets of this group.

Cross-cultural research on minority school achievement yields mixed findings on the motivational impact of future goal setting for students from disadvantaged minority groups. Relevant and recent motivational research, integrating Future Time Perspective Theory with Self-Determination Theory, has not yet been validated among minority students. To replicate across cultures the known motivational benefits of perceived instrumentality and internal regulation by distant future goals; to clarify when and how the future motivates minority students' educational performance. Participants in this study were 279 minority students (100 of Turkish and 179 of Moroccan origin) and 229 native Dutch students in Dutch secondary schools. Participants rated the importance of future goals, their perceptions of instrumentality, their task motivation and learning strategies. Dependent measures and their functional relations with future goal setting were simultaneously validated across minority and non-minority students, using structural equation modelling in multiple groups. As expected, Positive Perceived Instrumentality for the future increases task motivation and (indirectly) adaptive learning of both minority and non-minority students. But especially internally regulating future goals are strongly related to more task motivation and indirectly to more adaptive learning strategies. Our findings throw new light on the role of future goal setting in minority school careers: distant future goals enhance minority and non-minority students' motivation and learning, if students perceive positive instrumentality and if their schoolwork is internally regulated by future goals.

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

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.

THE NATIONAL MINORITY CONSULTATIVE MECHANISMS - THE COUNCILS OF NATIONAL MINORITIES IN BOSNIA AND HERZEGOVINA

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.

Exploring Discrimination and Mental Health Disparities Faced By Black Sexual Minority Women Using a Minority Stress Framework.

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.

Sexual minority-related victimization as a mediator of mental health disparities in sexual minority youth: a longitudinal analysis.

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

We examined the direct and indirect impact of minority stress on mental health and substance use among sexual minority women. A combination of snowball and targeted sampling strategies was used to recruit lesbian and bisexual women (N = 1,381) for a cross-sectional, online survey. Participants (M age = 33.54 years; 74% White) completed a questionnaire assessing gender expression, minority stressors (i.e., victimization, internalized homophobia, and concealment), social-psychological resources (i.e., social support, spirituality), and health-related outcomes. We used structural equation modeling to test associations among these factors, with gender expression as an antecedent and social-psychological resources as a mediator between minority stress and health. The final model demonstrated acceptable fit, χ²(79) = 414.00, p accounting for significant portions of the variance in mental health problems (56%) and substance use (14%), as well as the mediator social-psychological resources (24%). Beyond indirect effects of minority stress on health outcomes, direct links emerged between victimization and substance use and between internalized homophobia and substance use. Findings indicate a significant impact of minority stressors and social-psychological resources on mental health and substance use among sexual minority women. The results improve understanding of the distinct role of various minority stressors and their mechanisms on health outcomes. Health care professionals should assess for minority stress and coping resources and refer for evidence-based psychosocial treatments. (c) 2011 APA, all rights reserved.

According to the family stress model (Conger & Donnellan, 2007), low socioeconomic status (SES) predicts less-than-optimal parenting through family stress. Minority families generally come from lower SES backgrounds than majority families, and may experience additional stressors associated with their minority status, such as acculturation stress. The primary goal of this study was to test a minority family stress model with a general family stress pathway, as well as a pathway specific to ethnic minority families. The sample consisted of 107 Turkish-Dutch mothers and their 5- to 6-year-old children, and positive parenting was observed during a 7-min problem-solving task. In addition, mothers reported their daily hassles, psychological distress, and acculturation stress. The relation between SES and positive parenting was partially mediated by both general maternal psychological stress and maternal acculturation stress. Our study contributes to the argument that stressors specific to minority status should be considered in addition to more general demographic and family stressors in understanding parenting behavior in ethnic minority families.

Minority stressors, rumination, and psychological distress in monozygotic twins discordant for sexual minority status.

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.

Defining minors' abortion rights.

Science.gov (United States)

Rhodes, A M

1988-01-01

The right to abortion is confirmed in the Roe versus Wade case, by the US Supreme Court. It is a fundamental right of privacy but not an absolute right, and must consider state interests. During the first trimester of pregnancy abortion is a decision of the woman and her doctor. During the second trimester of pregnancy the state may control the abortion practice to protect the mothers health, and in the last trimester, it may prohibit abortion, except in cases where the mother's life or health are in danger. The states enacted laws, including one that required parents to give written consent for a unmarried minor's abortion. This law was struck down by the US Court, but laws on notification were upheld as long as there was alternative procedures where the minor's interests are upheld. Many of these law have been challenged successfully, where the minor was judged mature and where it served her best interests. The state must enact laws on parental notification that take into consideration basic rights of the minor woman. Health professionals and workers should be aware of these laws and should encourage the minor to let parents in on the decision making process where possible.

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.

Legislative vulnerability of minority groups.

Science.gov (United States)

Paula, Carlos Eduardo Artiaga; Silva, Ana Paula da; Bittar, Cléria Maria Lôbo

2017-12-01

Minorities are in an inferior position in society and therefore vulnerable in many aspects. This study analyzes legislative vulnerability and aims to categorize as "weak" or "strong" the protection conferred by law to the following minorities: elderly, disabled, LGBT, Indians, women, children/ adolescents and black people. In order to do so, it was developed a documental research in 30 federal laws in which legal provisions were searched to protect minorities. Next, the articles were organized in the following categories: civil, criminal, administrative, labor and procedural, to be analyzed afterwards. Legal protection was considered "strong" when there were legal provisions that observed the five categories and "weak" when it did not meet this criterion. It was noted that six groups have "strong" legislative protection, which elides the assertion that minorities are outside the law. The exception is the LGBT group, whose legislative protection is weak. In addition, consecrating rights through laws strengthens the institutional channels for minorities to demand their rights. Finally, it was observed that the legislative protection granted tominorities is not homogeneous but rather discriminatory, and there is an interference by the majority group in the rights regulation of vulnerable groups.

Workplace harassment: double jeopardy for minority women.

Berdahl, Jennifer L; Moore, Celia

2006-03-01

To date there have been no studies of how both sex and ethnicity might affect the incidence of both sexual and ethnic harassment at work. This article represents an effort to fill this gap. Data from employees at 5 organizations were used to test whether minority women are subject to double jeopardy at work, experiencing the most harassment because they are both women and members of a minority group. The results supported this prediction. Women experienced more sexual harassment than men, minorities experienced more ethnic harassment than Whites, and minority women experienced more harassment overall than majority men, minority men, and majority women.

Minor actinide transmutation on PWR burnable poison rods

International Nuclear Information System (INIS)

Hu, Wenchao; Liu, Bin; Ouyang, Xiaoping; Tu, Jing; Liu, Fang; Huang, Liming; Fu, Juan; Meng, Haiyan

2015-01-01

Highlights: • Key issues associated with MA transmutation are the appropriate loading pattern. • Commercial PWRs are the only choice to transmute MAs in large scale currently. • Considerable amount of MA can be loaded to PWR without disturbing k eff markedly. • Loading MA to PWR burnable poison rods for transmutation is an optimal loading pattern. - Abstract: Minor actinides are the primary contributors to long term radiotoxicity in spent fuel. The majority of commercial reactors in operation in the world are PWRs, so to study the minor actinide transmutation characteristics in the PWRs and ultimately realize the successful minor actinide transmutation in PWRs are crucial problem in the area of the nuclear waste disposal. The key issues associated with the minor actinide transmutation are the appropriate loading patterns when introducing minor actinides to the PWR core. We study two different minor actinide transmutation materials loading patterns on the PWR burnable poison rods, one is to coat a thin layer of minor actinide in the water gap between the zircaloy cladding and the stainless steel which is filled with water, another one is that minor actinides substitute for burnable poison directly within burnable poison rods. Simulation calculation indicates that the two loading patterns can load approximately equivalent to 5–6 PWR annual minor actinide yields without disturbing the PWR k eff markedly. The PWR k eff can return criticality again by slightly reducing the boric acid concentration in the coolant of PWR or removing some burnable poison rods without coating the minor actinide transmutation materials from PWR core. In other words, loading minor actinide transmutation material to PWR does not consume extra neutron, minor actinide just consumes the neutrons which absorbed by the removed control poisons. Both minor actinide loading patterns are technically feasible; most importantly do not need to modify the configuration of the PWR core and

Happiness and Sexual Minority Status.

Thomeer, Mieke Beth; Reczek, Corinne

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.

Dictionary of Minor Planet Names, Fifth Edition, is the official reference for the field of the IAU, which serves as the internationally recognised authority for assigning designations to celestial bodies and any surface features on them. The accelerating rate of the discovery of minor planets has not only made a new edition of this established compendium necessary but has also significantly altered its scope: this thoroughly revised edition concentrates on the approximately 10,000 minor planets that carry a name. It provides authoritative information about the basis for all names of minor planets. In addition to being of practical value for identification purposes, this collection provides a most interesting historical insight into the work of those astronomers who over two centuries vested their affinities in a rich and colorful variety of ingenious names, from heavenly goddesses to more prosaic constructions. The fifth edition serves as the primary reference, with plans for complementary booklets with newl...

Gallus, Silvano; Tramacere, Irene; Zuccaro, Piergiorgio; Colombo, Paolo; La Vecchia, Carlo

2009-01-01

One of the strategies to control tobacco is to limit purchase of cigarettes to minors. To understand the attitudes of Italian adults towards regulations to prevent minors from purchasing tobacco products, we added specific questions to the annual survey on smoking in Italy. During March-April 2007, we conducted a survey on smoking on 3,057 subjects representative of the Italian population aged > or = 15 years. Two specific questions were included, one investigating the attitudes towards the proposed legislation prohibiting purchase of tobacco to individuals under 18 years of age (instead of 16 years) as a policy to reduce smoking prevalence and consumption. The second question asked whether the current tobacco sales-to-minors law was observed. Overall, 78% of Italians believed that a restriction of the current tobacco sales-to-minors law could be moderately to extremely effective as a strategy to decrease smoking prevalence and consumption. More than 90% of Italians reported that they had never seen in their lifetime a retailer refusing to sell cigarettes to an adolescent or requesting the minor's identification or age. A restriction of the legislation, increasing to 18 years the minimum age for purchasing tobacco, would limit access to tobacco products by minors, only if adopted together with systematic and effective enforcement measures.

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

Minor actinide transmutation - a waste management option

International Nuclear Information System (INIS)

Koch, L.

1986-01-01

The incentive to recycle minor actinides results from the reduction of the long-term α-radiological risk rather than from a better utilization of the uranium resources. Nevertheless, the gain in generated electricity by minor actinide transmutation in a fast breeder reactor can compensate for the costs of their recovery and make-up into fuel elements. Different recycling options of minor actinides are discussed: transmutation in liquid metal fast breeder reactors (LMFBRs) is possible as long as plutonium is not recycled in light water reactors (LWRs). In this case a minor actinide burner with fuel of different composition has to be introduced. The development of appropriate minor actinide fuels and their properties are described. The irradiation experiments underway or planned are summarized. A review of minor actinide partitioning from the PUREX waste stream is given. From the present constraints of LMFBR technology a reduction of the long-term α-radiological risk by a factor of 200 is deduced relative to that from the direct storage of spent LWR fuel. Though the present accumulation of minor actinides is low, nuclear transmutation may be needed when nuclear energy production has grown. (orig.)

Minors and Sexting: Legal Implications.

Science.gov (United States)

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

2016-03-01

Sexting is the sending or forwarding of sexually explicit photographs or videos of the sender or someone known to the sender via cell phone. It has become common practice among young people, as cell phones are being given to adolescents at ever younger ages. Youths often send messages without giving appropriate thought to the content of the images. In studies on the subject, rates of minors who have sent sexual images range from 4 to 25 percent, depending on the age of the youths surveyed, the content of the messages and other factors. Because transferring and viewing sexually explicit material when the subject is a minor can be considered child pornography, there can be serious legal consequences. Several states have enacted legislation to help differentiate between child pornography and sexting by minors. The trend reflected in statutes has been that minors involved in sexting without other exacerbating circumstances should be charged with a less serious offense. There is no clear national consensus on how sexting by minors is adjudicated, and therefore we compared several statutes. Case examples are used to illustrate the range of legal outcomes, from felony charges to no charges. Two sexting episodes that were followed by suicide are described. We also address the role of the forensic mental health professional. © 2016 American Academy of Psychiatry and the Law.

Since the minor planets are believed to consist of primordial matter dating from the time of the formation of the solar system there is great interest in determining their composition. It is therefore necessary to calculate their densities, for which we need accurate masses and sizes. On the rare occasions when a minor planet occults a star, timed observations of the event from a number of observing sites enable an accurate size of the minor planet to be determined. (Auth.)

Sexual Minority Stress, Coping, and Physical Health Indicators.

Science.gov (United States)

Flenar, Delphia J; Tucker, Carolyn M; Williams, Jaime L

2017-12-01

Sexual minorities experience higher rates of several physical health problems compared to their heterosexual counterparts. The present study uses Meyer's Minority Stress Model (Psychological Bulletin, 129(5): 674-697, 2003) to examine physical health indicators among 250 adults who identified as sexual minorities. Study hypotheses include that sexual minority stress is predictive of two physical health indicators (i.e., engagement in a health-promoting lifestyle and number of physical health problems) and that planning (i.e., problem-focused) and social support coping will partially mediate the relationship between sexual minority stress and each physical health indicator. Results showed that as level of sexual minority stress increased, engagement in a health-promoting lifestyle decreased and the number of physical health problems increased. Planning and social support coping did not mediate these relationships; however, as levels of coping increased, engagement in a health-promoting lifestyle increased. These findings have implications for researchers and healthcare professionals in their efforts to promote the physical health of sexual minorities.

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.

Full Text Available The Constitution of the Republic of Slovenia mentions only Italian and Hungarian national minority and Roma community as holders of special collective minority rights. Special rights of the autochthonous Italian and Hungarian national minorities in Slovenia are defined in Article 64. Although data on the ethnic structure in Slovenia reflect more heterogeneous ethnic structure, members of other ethnic groups than Italian and Hungarian national communities and Roma community, at present, do not have the status of a national minority in the sense of collective holders of minority rights. In February 2018 the draft Act on the Implementation of Collective Cultural Rights of National Communities of the Nations of the Former Socialist Federal Republic of Yugoslavia in the Republic of Slovenia was prepared. The draft received a support within the National Parliament of the Republic of Slovenia for further consideration

Legal protection of informed consent of minors.

Science.gov (United States)

Osuna, Eduardo

2010-06-01

One of the pillars of healthcare provision is respect for the autonomy of the patient's wishes, which is given substance by the process of obtaining informed consent. Minors deserve special protection, entitled to basic rights and increasingly autonomous as they develop. In certain situations, minors are deemed matures and able to consent to treatment without the involvement of a parent or guardian. The assessment of competence would be based on the child's functional ability, not on age or outcome of the decision. This manuscript includes a brief analysis of legal perspectives on informed consent of minors, and minors' capacities to make medical decisions.

Considerations on informed consent in different situations as refusing treatment and termination of pregnancy by female children are analyzed.

Disparities in health system input between minority and non-minority counties and their effects on maternal mortality in Sichuan province of western China.

Science.gov (United States)

Ren, Yan; Qian, Ping; Duan, Zhanqi; Zhao, Ziling; Pan, Jay; Yang, Min

2017-09-29

The maternal mortality rate (MMR) markedly decreased in China, but there has been a significant imbalance among different geographic regions (east, central and west regions), and the mortality in the western region remains high. This study aims to examine how much disparity in the health system and MMR between ethnic minority and non-minority counties exists in Sichuan province of western China and measures conceivable commitments of the health system determinants of the disparity in MMR. The MMR and health system data of 67 minority and 116 non-minority counties were taken from Sichuan provincial official sources. The 2-level Poisson regression model was used to identify health system determinants. A series of nested models with different health system factors were fitted to decide contribution of each factor to the disparity in MMR. The MMR decreased over the last decade, with the fastest declining rate from 2006 to 2010. The minority counties experienced higher raw MMR in 2002 than non-minority counties (94.4 VS. 58.2), which still remained higher in 2014 (35.7 VS. 14.3), but the disparity of raw MMR between minority and non-minority counties decreased from 36.2 to 21.4. The better socio-economic condition, more health human resources and higher maternal health care services rate were associated with lower MMR. Hospital delivery rate alone explained 74.5% of the difference in MMR between minority and non-minority counties. All health system indicators together explained 97.6% of the ethnic difference in MMR, 59.8% in the change trend, and 66.3% county level variation respectively. Hospital delivery rate mainly determined disparity in MMR between minority and non-minority counties in Sichuan province. Increasing hospital birth rates among ethnic minority counties may narrow the disparity in MMR by more than two-thirds of the current level.

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.

Minority game with SK interactions

International Nuclear Information System (INIS)

Menezes, Pedro Castro; Sherrington, David

2013-01-01

A batch minority game with fake random history and additional SK-like quenched interaction is introduced and analysed. A mixing parameter λ quantifies the admixture and dictates the relative dominance of the two contributions: if λ → 0, agent decisions are based on their strategies and point-scores alone, as in the pure minority game, whereas for λ > 0 the agents also communicate with each other directly and update their points accordingly. Keeping the minority game dynamics in which the agents’ points are updated in parallel at each time step, the aim is to understand what happens if instead of simply using the normal strategy-based decisions, the agents also take account of an ‘effective field’ generated by the other agents. It is shown that the SK interaction introduces a ‘noise’ term which is broader than that in the normal minority game and which furthermore kills the normal phase transition. It is also shown that the same effect would occur if, instead of an SK interaction, Gaussian-distributed quenched random fields are added. By calculating order parameters in the time-translational invariant phase we show that the system is persistent in a ergodic phase. Both simulational and analytical results are presented. (paper)

DNA minor groove alkylating agents.

Science.gov (United States)

Denny, W A

2001-04-01

Recent work on a number of different classes of anticancer agents that alkylate DNA in the minor groove is reviewed. There has been much work with nitrogen mustards, where attachment of the mustard unit to carrier molecules can change the normal patterns of both regio- and sequence-selectivity, from reaction primarily at most guanine N7 sites in the major groove to a few adenine N3 sites at the 3'-end of poly(A/T) sequences in the minor groove. Carrier molecules discussed for mustards are intercalators, polypyrroles, polyimidazoles, bis(benzimidazoles), polybenzamides and anilinoquinolinium salts. In contrast, similar targeting of pyrrolizidine alkylators by a variety of carriers has little effect of their patterns of alkylation (at the 2-amino group of guanine). Recent work on the pyrrolobenzodiazepine and cyclopropaindolone classes of natural product minor groove binders is also reviewed.

Bussing of Ethnic Minority Children

DEFF Research Database (Denmark)

Jacobsen, Gro Hellesdatter

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...

Transmutation of minor actinide using thorium fueled BWR core

International Nuclear Information System (INIS)

Susilo, Jati

2002-01-01

One of the methods to conduct transmutation of minor actinide is the use of BWR with thorium fuel. Thorium fuel has a specific behaviour of producing a little secondary minor actinides. Transmutation of minor actinide is done by loading it in the BWR with thorium fuel through two methods, namely close recycle and accumulation recycle. The calculation of minor actinide composition produced, weigh of minor actinide transmuted, and percentage of reminder transmutation was carried SRAC. The calculations were done to equivalent cell modeling from one fuel rod of BWR. The results show that minor actinide transmutation is more effective using thorium fuel than uranium fuel, through both close recycle and accumulation recycle. Minor actinide transmutation weight show that the same value for those recycle for 5th recycle. And most of all minor actinide produced from 5 unit BWR uranium fuel can transmuted in the 6 t h of close recycle. And, the minimal value of excess reactivity of the core is 12,15 % Δk/k, that is possible value for core operation

2014-01-01

In the present work, the prospects of ZnS:Mn nanocrystals capped with L- serine, a bio-compatible amino acid, synthesized by wet chemical route, as efficient fluorescent probes for plant cell biological studies have been investigated. The present synthesis route using bio-compatible material is a low cost and easy to control method. The colloidal stability of the capped nano crystals is very good as they remain stable without settling down for long time. It is observed that L- serine significantly modifies the structural and optical characteristics of the ZnS:Mn nanocrystals and hence is suitable as a bio-compatible capping agent. The structural properties of L- serine capped nanocrystals were investigated by XRD technique. The size of the L- serine capped ZnS:Mn nanocrystals is found to be around 2 nm . The optical characterization of the nanocrystals was carried out on the basis of photoluminescence (PL) spectroscopic studies. The intense photoluminescence emission observed around 597nm for L-serine capped ZnS:Mn offers high prospects of applications in bio-imaging fields. The unique optical properties of nanoparticles make them appealing as in vivo and in vitro fluorophores in a variety of biological investigations. In the present study, L-serine capped ZnS:Mn nanocrystals were used as a staining dye in fluorescent microscope for observing cell division, cell structure etc. These nanocrystals were also incorporated into the culture media along with the normal auxin- cytokinin hormone combinations in Murashige and Skoog (MS) medium for micropropagation of Bacopa monnieri Linn. (Brahmi:Scrophulariaceae), an Ayurvedic medicine. The results suggest that L-serine capped ZnS:Mn nanocrystals can act as efficient enhancers towards quick callusing and shoot proliferation.

Teaching minority children hygiene: investigating hygiene education in kindergartens and homes of ethnic minority children in northern Vietnam.

Science.gov (United States)

Rheinländer, Thilde; Samuelsen, Helle; Dalsgaard, Anders; Konradsen, Flemming

2015-01-01

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

[Judicial framework for medical decision-making concerning minors].

Science.gov (United States)

Sirvent, N; Bérard, E

2010-02-01

One aim of the law promulgated in France on March 4, 2002 concerning patients' rights and the quality of the health care system was to reconsider the bases of the physician-patient relationship. The new legal framework recommends establishment of a true dialogue between the two protagonists, and it assigns decisional priority to the patient rather than to the physician or third parties. In the case of minors, the principle of parental authority requires that the physician consults the holders of this authority before making any medical decision. However, the law of March 4, 2002 also reinforced the participation of minors in medical decisions concerning them. The lawmaker explicitly envisaged the possibility of overruling the principle of parental authority. This new "balance of power" obliges the physician to inform the minor of his or her medical condition in a manner appropriate to the child's degree of maturity. The minor may even put forward the principle of medical secrecy to prevent the sharing of information with his or her parents. This new "autonomy" of minors gives rise to at least two reservations: i) the difficulty involved in assessment of a minor's degree of discernment; ii) the minor's vulnerability with respect to his or her entourage.

To study the clinical features of minor salivary gland tumors and to discuss the treatment modalities for these tumors. Retrospective analysis of 54 cases with minor salivary gland tumor operated in our hospital from 1997 to 2004. Among 54 cases with minor salivary gland tumors in this series, 16 patients lost of follow up. Among the remaining 38 patients, 2 patients with nasal cavity adenoid cystic carcinoma died of tumor recurrence 2 and 3 years after the surgery respectively, one patient with laryngeal myoepithelial carcinoma died of tumor recurrence 3 years after the surgery and one patient with paranasal sinus mucoepidermoid carcinoma died of recurrence 17 months after the surgery. Two patients with paranasal sinus adenoid cystic carcinoma recurred after the primary surgery and were survived without tumor after salvage surgery. The other patients survived with no tumor recurrence. While different histopathology of minor salivary gland tumors were found in this group, malignant tumors were predominant, accounting for 81.4%. The choice of treatment for minor salivary gland tumors depends upon the location and the histopathology of the tumors. The treatment policy for benign tumors is simple tumor excision, while that for malignant tumors is surgery combined with pre- or post-operative radiation therapy. Complete surgical resection of tumor masses and tumor free margin is essential for successful treatment of malignant minor salivary gland tumors.

Limited rights of minors in the Dutch healthcare.

Brands, Wolter; Brands, Marieke; Brands-Bottema, Gea

2014-11-30

In many countries, if not all, the autonomy of minors is limited. Especially in countries with comprehensive legislation in the field of health law the (lack of) autonomy of minors may create challenges. These problems become more complex if the costs of treatment are not paid by the government or covered by insurance. Some challenges are: At what age is a minor able to decide about his health? As not every treatment is the same, how should the system take this into account? The Netherlands has a long history of very comprehensive health care legislation. This legislation includes a section about the treatment of minors that addresses the questions of the conditions in which the autonomy of minors is limited. Though this legislation is limited to the Netherlands other countries face the same challenges.

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

Science.gov (United States)

Goldbach, J T; Gibbs, J J

2015-09-01

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

Own education institutions as an option for minority groups

Directory of Open Access Journals (Sweden)

H.J. Steyn

1998-03-01

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.

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?

Prevalence of dating violence among sexual minority youth: variation across gender, sexual minority identity and gender of sexual partners.

Science.gov (United States)

Martin-Storey, Alexa

2015-01-01

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.

Sexual minorities (mostly heterosexual, bisexual, lesbian/gay) are more likely than heterosexuals to have adverse mental health, which may be related to minority stress. We used longitudinal data from 1461 sexual minority women and men, aged 22-30 years, from Wave 2010 of the Growing Up Today Study, to examine associations between sexual minority stressors and mental health. We hypothesized that sexual minority stressors (earlier timing of sexual orientation developmental milestones categorized into early adolescence, middle adolescence, late adolescence/young adulthood; greater sexual orientation mobility; more bullying victimization) would be positively associated with mental health outcomes (depressive and anxious symptoms). Linear regression models stratified by gender and sexual orientation were fit via generalized estimating equations and controlled for age and race/ethnicity. Models were fit for each stressor predicting each mental health outcome. Reaching sexual minority milestones in early versus middle adolescence was associated with greater depressive and anxious symptoms among lesbians and gay men. Reaching sexual minority milestones in late adolescence/young adulthood versus middle adolescence was associated with greater depressive symptoms among lesbians, but fewer depressive and anxious symptoms among gay men. Greater sexual orientation mobility was associated with greater depressive symptoms among mostly heterosexual women. More bullying victimization was associated with greater depressive symptoms among bisexual women and with greater anxious symptoms among mostly heterosexual women. Sexual minority stressors are associated with adverse mental health among some sexual minority young adults. More research is needed to understand what may be protecting some subgroups from the mental health effects of sexual minority stressors.

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.

Evolution of plastid gene rps2 in a lineage of hemiparasitic and holoparasitic plants: Many losses of photosynthesis and complex patterns of rate variation

Science.gov (United States)

dePamphilis, Claude W.; Young, Nelson D.; Wolfe, Andrea D.

1997-01-01

The plastid genomes of some nonphotosynthetic parasitic plants have experienced an extreme reduction in gene content and an increase in evolutionary rate of remaining genes. Nothing is known of the dynamics of these events or whether either is a direct outcome of the loss of photosynthesis. The parasitic Scrophulariaceae and Orobanchaceae, representing a continuum of heterotrophic ability ranging from photosynthetic hemiparasites to nonphotosynthetic holoparasites, are used to investigate these issues. We present a phylogenetic hypothesis for parasitic Scrophulariaceae and Orobanchaceae based on sequences of the plastid gene rps2, encoding the S2 subunit of the plastid ribosome. Parasitic Scrophulariaceae and Orobanchaceae form a monophyletic group in which parasitism can be inferred to have evolved once. Holoparasitism has evolved independently at least five times, with certain holoparasitic lineages representing single species, genera, and collections of nonphotosynthetic genera. Evolutionary loss of the photosynthetic gene rbcL is limited to a subset of holoparasitic lineages, with several holoparasites retaining a full length rbcL sequence. In contrast, the translational gene rps2 is retained in all plants investigated but has experienced rate accelerations in several hemi- as well as holoparasitic lineages, suggesting that there may be substantial molecular evolutionary changes to the plastid genome of parasites before the loss of photosynthesis. Independent patterns of synonymous and nonsynonymous rate acceleration in rps2 point to distinct mechanisms underlying rate variation in different lineages. Parasitic Scrophulariaceae (including the traditional Orobanchaceae) provide a rich platform for the investigation of molecular evolutionary process, gene function, and the evolution of parasitism.

Variation in Subjective Aging by Sexual Minority Status.

Science.gov (United States)

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.

Recruitment of minority physicians into careers in internal medicine.

Science.gov (United States)

Potts, J T

1992-06-15

Despite some initial success in the early 1970s, the important goal of increasing the numbers of underrepresented minorities in medical school and on medical faculties has stalled short of proportionate representation. To further the current efforts of the Association of Professors in Medicine (APM) and other national medical groups that are devoted to improving the numbers of minorities in medicine, ideas and program information must be shared among institutions. In this spirit, we review our experience at Massachusetts General Hospital. We found that the first step toward this goal must be an institutional commitment based on increased awareness and on special effort focused on housestaff recruitment. Once the numbers of minorities increase, the department chairperson, training program directors, and other involved faculty can work with younger minority physicians; the cooperative relationship thus created can guide the development of a strong minority recruitment program without requiring an undue time commitment from minority trainees and faculty. The APM has a combined goal: to achieve early practical results in individual departments, to play a catalytic role with the community and other national medical organizations, and to increase the number of minorities entering medical school and careers in medicine generally.

THE DRAFT LAW ON THE STATUS OF NATIONAL MINORITIES VERSUS THE REAL CHALLENGES OF THE SYSTEM FOR THE PROTECTION OF MINORITIES

Directory of Open Access Journals (Sweden)

Gabriel ANDREESCU

2011-12-01

Full Text Available The study proposes an in-depth discussion of the provisions of the Draft Status of National Minorities: the definition of national minorities, the cultural autonomy system, the monopoly of political and cultural rights, and lack of transparency in the resources usage, the statements of individuals concerning their affiliation to a national community, the provisions dealing with religions “specific” to minorities, and the status of national minorities as constitutive factors of the Romanian state. The intention to reform the system for the protection of national minorities by adding cultural autonomy to other provisions is a positive one. However, the solutions put forward are dissatisfying. The Draft Status destroys democracy within the minority communities; reinforces the status quo where it should be questioned; extends the monopoly of political groups regarding decision-making in the cultural and educational areas; creates the conditions for increased ethnic business and leads to unreasonably higher costs of the national minority protection system compared to the benefits. Particularly important is the fact that the Draft Status does not tackle the specificity of the two big “nationalizing minorities”, Hungarians and Roma population. Hungarians are experiencing a continuous population decrease and are concerned about the decline of the old Hungarian civilization in Transylvania. The Roma population is facing severe issues regarding social status and poverty and need to be provided with an environment in which this fragmented community may mobilize. They need creative solutions for institutionalization.

2005-04-01

Recruitment of minority participants for clinical research studies has been the topic of several analytical works. Yet retention of participants, most notably minority and underserved populations, is less reported and understood, even though these populations have elevated health risks. This article describes two related, intervention-based formative research projects in which researchers used treatment theory to address issues of recruitment and retention of minority women participants in an exercise program to reduce obesity. Treatment theory incorporates a model of health promotion that allows investigators to identify and control sources of extraneous variables. The authors' research demonstrates that treatment theory can improve retention of minority women participants by considering critical inputs, mediating processes, and substantive participant characteristics in intervention design.

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...

Minors' rights in medical decision making.

Science.gov (United States)

Hickey, Kathryn

2007-01-01

In the past, minors were not considered legally capable of making medical decisions and were viewed as incompetent because of their age. The authority to consent or refuse treatment for a minor remained with a parent or guardian. This parental authority was derived from the constitutional right to privacy regarding family matters, common law rule, and a general presumption that parents or guardians will act in the best interest of their incompetent child. However, over the years, the courts have gradually recognized that children younger than 18 years who show maturity and competence deserve a voice in determining their course of medical treatment. This article will explore the rights and interests of minors, parents, and the state in medical decision making and will address implications for nursing administrators and leaders.

NATIONAL MINORITIES IN THE LAW OF THE EC/EU

Directory of Open Access Journals (Sweden)

Daniel Šmihula

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.

National minorities in legislation of Bosnia and Herzegovina

Nagradić Slobodan

2015-01-01

Full Text Available There are 17 recognized national minorities living and working in Bosnia and Herzegovina. At least, they have been enumerated, identified and sanctioned as such by the Law on the Protection of Rights of National Minorities adopted by the Parliamentary Assembly of Bosnia and Herzegovina in 2003. Apart from that law, the rights of national minorities and its members have also been regulated by the whole set of many different laws, from the election, criminal, education and other identity-related laws to the laws addressing the specific areas and/or life issues, all adopted at the level of the state, the entities, the cantons, and the Brcko District of BiH. This paper analyses the content, the significance, and the legal and sociopolitical implications of certain provisions of the Law on the Protection of Rights of National Minorities from the sociological and political views and methods, as well as the relation and the impact of its norms on social sphere and individual existence (in politics, education, culture, the media, employment etc. of minority members within a multi-specific and asymmetric state as post-Dayton Bosnia and Herzegovina. The causa finalis of this tractatus's narrative is to give a better understanding of human rights of minorities, their etiology and determination.

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

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

Low velocity encounters of minor bodies with the outer planets

Carusi, A.; Perozzi, E.; Valsecchi, G.B.

1983-01-01

Previous studies of close encounters of minor bodies with Jupiter have shown that the perturbations are stronger either if the encounter is very deep or if the velocity of the minor body relative to the planet is low. In the present research the author investigates the effects of low velocity encounters between fictitious minor bodies and the four outer planets. Two possible outcomes of this type of encounter are the temporary satellite capture of the minor body by the planet, and the exchange of perihelion with aphelion of the minor body orbit. Different occurrence rates of these processes are found for different planets, and the implications for the orbital evolution of minor bodies in the outer Solar System are discussed. (Auth.)

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

Sextortion of Minors: Characteristics and Dynamics.

Wolak, Janis; Finkelhor, David; Walsh, Wendy; Treitman, Leah

2018-01-01

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.

Minors and social networks: legal questions

Full Text Available The participation in a company increasingly technological does that numerous questions appear on the protection of the most vulnerable subjects, between them the minors. 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.

A review of research on smoking behavior in three demographic groups of veterans: women, racial/ethnic minorities, and sexual orientation minorities.

Veterans comprise a large segment of the U.S. population and smoke at high rates. One significant way to reduce healthcare costs and improve the health of veterans is to reduce smoking-related illnesses for smokers who have high smoking rates and/or face disproportionate smoking consequences (e.g. women, racial/ethnic minorities, sexual orientation minorities). We reviewed published studies of smoking behavior in three demographic subgroups of veterans - women, racial/ethnic minorities, and sexual orientation minorities - to synthesize current knowledge and identify areas in need of more research. A MEDLINE search identified papers on smoking and veterans published through 31 December 2014. Twenty-five studies were identified that focused on gender (n = 17), race/ethnicity (n = 6), or sexual orientation (n = 2). Female and sexual orientation minority veterans reported higher rates of smoking than non-veteran women and sexual orientation majority veterans, respectively. Veterans appeared to be offered VA smoking cessation services equally by gender and race. Few studies examined smoking behavior by race/ethnicity or sexual orientation. Little information was identified examining the outcomes of specific smoking treatments for any group. There is a need for more research on all aspects of smoking and quit behavior for women, racial/ethnic minorities, and sexual orientation minority veterans. The high rates of smoking by these groups of veterans suggest that they may benefit from motivational interventions aimed at increasing quit attempts and longer and more intense treatments to maximize outcomes. Learning more about these veterans can help reduce costs for those who experience greater consequences of smoking.

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.

Full Text Available Lagochilascaris minor is the causative agent of lagochilascariosis, a disease that affects the neck region and causes festering abscesses, with eggs, adult parasites and L3/L4 larvae within the purulent exudates. Today, mice are considered to be intermediate hosts for the parasite. C57BL/6 mice produce immunoglobulin IgM, IgA and IgG against the crude extract of the parasite; on the other hand, antibodies produced against the secreted/excreted antigens of Lagochilascaris minor present lower levels of IgM, IgA and IgG. This is the first description of antibody detection against different antigens of Lagochilascaris minor.Lagochilascaris minor é o agente etiológico da lagochilascariose, uma doença que afeta a região do pescoço causando abscessos exudativos com presença de ovos, parasitos adultos e larvas nos de exudatos purulentos. Hoje em dia, camundongos são considerados os hospedeiros intermediários para o parasita. Camundongos C57BL/6 produziram imunoglobulinas IgM, IgA e IgG contra o extrato bruto do parasita; por outro lado, anticorpos produzidos contra os antígenos secretados/excretados de Lagochilascaris minor apresentaram níveis mais baixos de IgM, IgA e IgG. Esta é a primeira descrição da detecção de anticorpos contra diferentes antígenos de Lagochilascaris minor.

Vojvodina’s national minorities: Current realities and future prospects

Directory of Open Access Journals (Sweden)

Petsinis Vasilis

2004-01-01

Full Text Available In this article, a critical overview of the situation of the national minorities resident in the Serbian autonomous province of Vojvodina is pursued. First of all, the novel legal framework with regard to national minorities, on the federal as well as the provincial level, is outlined. Then, the state of education in Vojvodina’s minority languages, as well as the situation of the national minorities’ media and press, is assessed. What the author tries to demonstrate is that the effective safeguard of the collective identity of Vojvodina’s national minorities primarily relies on two factors: a. the full implementation of the novel legal (federal as well as provincial provisions; b. the attitude of the national minorities themselves towards the question of preserving their group identities.

Major and minor axis kinematics of 22 ellipticals

International Nuclear Information System (INIS)

Franx, M.; Illingworth, G.; Heckman, T.

1989-01-01

Rotation curves and velocity dispersion profiles have been determined for the major and the minor axes of 22 elliptical galaxies. Rotation was detected in all but one galaxy, even though the sample was biased toward round ellipticals. Minor axis rotation larger than major axis rotation was measured in two galaxies, NGC 4406 and NGC 7507. Roughly 10 percent of ellipticals may show large minor axis velocities relative to those on the major axis. A simple model is used to derive a rotational axis from the observed minor and major axis velocities to a typical accuracy of 6 deg. The rotational and photometric minor axes aligned to better than 10 deg for 60 percent of the sample, implying that the direction of the angular momentum is related to the orientation of the figure of the galaxy. IC 1459 has a kinematically distinct core with its angular momentum opposite to the angular momentum of the outer parts, and NGC 4406 has a core with its angular momentum perpendicular to that of the outer parts. 46 refs

Assumptions about culture in discourse on ethnic minority health.

Science.gov (United States)

Jaeger, Kirsten

2013-01-01

This paper is interested in the way the concept of culture is deployed in documents aimed at investigating, informing on and promoting aspects of ethnic minority health. Within a health-political discourse focusing increasingly on individual lifestyles, ethnic minority health became subject to increased political and professional interest in the last decades of the twentieth and the first decade of the twenty-first century. Analysis of the discourse on ethnic minority health emerging in five texts addressing health professionals shows that the culture of ethnic minority citizens is primarily seen as contributing to low levels of knowledge about health and to adverse health behavior. Thus, the texts present cultural beliefs and practices as contributing to the high prevalence of lifestyle diseases among ethnic minority population groups. The analysis, however, demonstrates that a more nuanced discourse is evolving, taking the complexity of the culture concept into account. In accordance with Danish health-political priorities, the most recent text analyzed in this study promotes an individualistic approach to both ethnic minority and Danish ethnic majority citizens.

Okuda, Mayumi; Liu, Weiwei; Cisewski, Jodi A; Segura, Luis; Storr, Carla L; Martins, Silvia S

2016-09-01

Previous studies demonstrate disparities in health and health services including gambling disorders (GD) among ethnic and racial minority groups. In this review, we summarize studies examining the prevalence of GD across different ethnic and racial minorities. We describe the sociodemographic subgroup variations at heightened risk for GD and factors associated with GD in racial and ethnic minority groups including gambling availability, comorbid substance use, psychiatric conditions, stress, acculturation, and differences in cultural values and cognitions. We found that research of GD among minority groups is scant, and the prevalence of GD among these groups is at a magnitude of concern. Racial and ethnic minority status in it of itself is not a risk factor for GD but may be a proxy for underlying potential risk factors. The need for prevention and treatment programs for different cultural group remains unmet.

Principal minors and rhombus tilings

International Nuclear Information System (INIS)

Kenyon, Richard; Pemantle, Robin

2014-01-01

The algebraic relations between the principal minors of a generic n × n matrix are somewhat mysterious, see e.g. Lin and Sturmfels (2009 J. Algebra 322 4121–31). We show, however, that by adding in certain almost principal minors, the ideal of relations is generated by translations of a single relation, the so-called hexahedron relation, which is a composition of six cluster mutations. We give in particular a Laurent-polynomial parameterization of the space of n × n matrices, whose parameters consist of certain principal and almost principal minors. The parameters naturally live on vertices and faces of the tiles in a rhombus tiling of a convex 2n-gon. A matrix is associated to an equivalence class of tilings, all related to each other by Yang–Baxter-like transformations. By specializing the initial data we can similarly parameterize the space of Hermitian symmetric matrices over R,C or H the quaternions. Moreover by further specialization we can parametrize the space of positive definite matrices over these rings. This article is part of a special issue of Journal of Physics A: Mathematical and Theoretical devoted to ‘Cluster algebras mathematical physics’. (paper)

First evidence for glial pathology in late life minor depression:S100B is increased in males with minor depression

2015-10-01

Full Text Available Minor depression is diagnosed when a patient suffers from two to four depressive symptoms for at least two weeks. Though minor depression is a widespread phenomenon, its pathophysiology has hardly been studied. To get a first insight into the pathophysiological mechanisms underlying this disorder we assessed serum levels of biomarkers for plasticity, glial and neuronal function: brain-derived neurotrophic factor (BDNF, S100B and neuron specific enolase (NSE. 27 subjects with minor depressive episode and 82 healthy subjects over 60 years of age were selected from the database of the Leipzig population-based study of civilization diseases (LIFE. Serum levels of BDNF, S100B and NSE were compared between groups, and correlated with age, body-mass index, and degree of white matter hyperintensities (score on Fazekas scale. S100B was significantly increased in males with minor depression in comparison to healthy males, whereas other biomarkers did not differ between groups (p=0.10-0.66. NSE correlated with Fazekas score in patients with minor depression (r=0.436, p=0.048 and in the whole sample (r=0.252, p=0.019. S100B correlated with body mass index (r=0.246, p=0.031 and with age in healthy subjects (r=0.345, p=0.002. Increased S100B in males with minor depression, without alterations in BDNF and NSE, supports the glial hypothesis of depression. Correlation between white matter hyperintensities and NSE underscores the vascular hypothesis of late life depression.

Payne, J L; Nowacki, C M; Girotti, J A; Townsel, J; Plagge, J C; Beckham, T W

1986-05-01

The University of Illinois College of Medicine has operated a program since 1969 to recruit minority students into the college and to increase the graduation rates of these students once they enroll. Known as the Medical Opportunities Program (MOP) until 1978, the program was expanded in 1978 and renamed the Urban Health Program (UHP). The authors of the present paper discuss the results of these programs, particularly the effect of granting minority students delays in completing graduation requirements. The MOP (1969 through 1978) increased graduation rates for minority students from 55 percent for those who graduated on time to 81 percent for both on-time and delayed graduates. Under the first seven years of the UHP (1979 through 1985), more minority students have been offered places, and more have enrolled than in the 10 years of the MOP. The retention rate under the UHP, if it holds, will be higher than that under the MOP. For the combined MOP-UHP period, the retention rate for minority students was 88 percent; 69.8 percent of the graduates were on time, and 30.2 were delayed.

Casting of metallic fuel containing minor actinide additions

International Nuclear Information System (INIS)

Trybus, C.L.; Henslee, S.P.; Sanecki, J.E.

1992-01-01

A significant attribute of the Integral Fast Reactor (IFR) concept is the transmutation of long-lived minor actinide fission products. These isotopes require isolation for thousands of years, and if they could be removed from the waste, disposal problems would be reduced. The IFR utilizes pyroprocessing of metallic fuel to separate auranium, plutonium, and the minor actinides from nonfissionable constituents. These materials are reintroduced into the fuel and reirradiated. Spent IFR fuel is expected to contain low levels of americium, neptunium, and curium because the hard neutron spectrum should transmute these isotopes as they are produced. This opens the possibility of using an IFR to trnasmute minor actinide waste from conventional light water reactors (LWRs). A standard IFR fuel is based on the alloy U-20% Pu-10% Zr (in weight percent). A metallic fuel system eases the requirements for reprocessing methods and enables the minor actinide metals to be incorporated into the fuel with simple modifications to the basic fuel casting process. In this paper, the authors report the initial casting experience with minor actinide element addition to an IFR U-Pu-Zr metallic fuel

Minority recruitment and retention in dietetics: issues and interventions.

Science.gov (United States)

Greenwald, H P; Davis, R A

2000-08-01

To better understand the reasons why minorities and males are underrepresented among registered dietitians (RDs) and dietetic technicians, registered, (DTRs) and to develop focuses for intervention, the investigators performed a telephone survey of newly credentialed RDs and DTRs and directors of RD and DTR education programs. Using lists of students recruited by the American Dietetic Association for participation in the survey, the investigators interviewed 83 RDs and DTRs and 20 education program directors. RDs and DTRs attributed minority underrepresentation primarily to the field's lack of visibility and underrepresentation of men to the traditional association with women. Education program directors attributed minority underrepresentation to educational disadvantages, particularly in scientific subjects. Findings from this study support program-level interventions such as increasing program flexibility, initiating outreach to K-12 schools and lower-division college students, providing tutoring in a nondemeaning atmosphere, and visibly expressing commitment to minority representation. More fundamental changes in the profession itself appear necessary for large-scale increases in minority representation. These include increasing internship opportunities; raising the profession's level of remuneration, prestige, and independence; increasing scholarship support; and advertising nationally through channels capable of reaching minorities.

Boron accumulation by Lemna minor L. under salt stress.

2018-06-12

Excess boron (B) is toxic to aquatic organisms and humans. Boron is often present in water with high salinity. To evaluate the potential of duckweed (Lemna minor L.) for removing B from water under salt stress, we cultured duckweed in water with 2 mg/L of B and sodium chloride (NaCl) concentrations ranging from 0 to 200 mM for 4 days. The results show that with increasing salinity, the capacity of L. minor to accumulate B initially decreased and then increased. L. minor used different mechanisms to accumulate boron at lower and higher levels of salt stress. The growth and chlorophyll synthesis of L. minor were significantly inhibited when the concentration of NaCl reached 100 mM. Our results suggest that L. minor is suitable for the accumulation of B when NaCl salinity is below 100 mM.

The results of chest radiography in 581 patients with blunt minor thoracic trauma were reviewed. Frontal and lateral views of the chest indicated pathology in 72 patients (12.4%). Pneumothorax was present in 16 patients; 4 had hemothorax. The physical examination and the results of chest radiography were not in accordance because in 6(30%) of the 20 patients with hemo/-pneumothorax the physical examination was normal. Consequently there is wide indication for chest radiography after minor blunt chest trauma.

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

Resilience to Discrimination and Rejection Among Young Sexual Minority Males and Transgender Females: A Qualitative Study on Coping With Minority Stress.

Science.gov (United States)

Bry, Laura Jane; Mustanski, Brian; Garofalo, Robert; Burns, Michelle Nicole

2017-09-13

Sexual minority and transgender status is associated with mental health disparities, which have been empirically and theoretically linked to stressors related to social stigma. Despite exposure to these unique stressors, many sexual minority and transgender individuals will not experience mental health disorders in their lifetime. Little is known about the specific processes that sexual minority and transgender youth use to maintain their wellbeing in the presence of discrimination and rejection. Semistructured interviews were conducted with 10 sexual minority males and transgender females aged 18-22 years, who currently met criteria for an operationalized definition of resilience to depression and anxiety. Data were analyzed qualitatively, yielding information related to a wide variety of problem-solving, support-seeking, and accommodative coping strategies employed by youth in the face of social stigma. Results are discussed in light of their clinical implications.

Ethnic Minorities' Impression Management in the Interview: Helping or Hindering?

Science.gov (United States)

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.

Production and measurement of minor actinides in the commercial fuel cycle

International Nuclear Information System (INIS)

Stanbro, W.D.

1997-03-01

The minor actinide elements, particularly neptunium and americium, are produced as a normal byproduct of the operation of thermal power reactors. Because of the existence of long-lived isotopes of these elements, they constitute the major sources of the residual radiation in spent fuel or in wastes resulting from reprocessing. This has led to examinations by some countries of the possibility of separating the minor actinides from waste products. The papers found in this report address the production of minor actinides in common thermal power reactors as well as approaches to measure these materials in various media. The first paper in this volume, open-quotes Production of Minor Actinides in the Commercial Fuel Cycle,close quotes uses calculations with the ORIGEN2 reactor and decay code to estimate the amounts of minor actinides in spent fuel and separated plutonium as a function of reactor irradiation and the time after discharge. The second paper, open-quotes Destructive Assay of Minor Actinides,close quotes describes a number of promising approaches for the chemical analysis of minor actinides in the various forms in which they are found at reprocessing plants. The next paper, open-quotes Hybrid KED/XRF Measurement of Minor Actinides in Reprocessing Plants,close quotes uses the results of a simulation model to examine the possible applications of the hybrid KED/XRF instrument to the determination of minor actinides in some of the solutions found in reprocessing plants. In open-quotes Calorimetric Assay of Minor Actinides,close quotes the authors show some possible extensions of this powerful technique beyond the normal plutonium assays to include the minor actinides. Finally, the last paper in this volume, open-quotes Environment Measurements of Transuranic Nuclides,close quotes discusses what is known about the levels of the minor actinides in the environment and ways to analyze for these materials in environmental matrices

Burning minor actinides in a HTR energy spectrum

International Nuclear Information System (INIS)

Pohl, Christoph; Rütten, H. Jochem

2012-01-01

Highlights: ► Burn-up analysis for varying plutonium/minor actinide fuel compositions. ► The influence of varying heavy metal fuel element loads is investigated. ► Significant burn-up via radiative capture and subsequently fission is observed. ► Difference observed between fuel element burn-up and total actinide burning rate. - Abstract: The generation of nuclear energy by means of the existing nuclear reactor systems is based mainly on the fission of U-235. But this comes along with the capture of neutrons by the U-238 faction and results in a build-up of plutonium isotopes and minor actinides as neptunium, americium and curium. These actinides are dominant for the long time assessment of the radiological risk of a final disposal therefore a minimization of the long living isotopes is aspired. Burning the actinides in a high temperature helium cooled graphite moderated reactor (HTR) is one of these options. The use of plutonium isotopes to sustain the criticality of the system is intended to avoid on the one hand highly enriched uranium because of international regulations and on the other hand low enriched uranium because of the build up of new actinides from neutron capture in the U-238 fraction. Because initial minor actinide isotopes are typically not fissionable by thermal neutrons the idea is to fission instead the intermediate isotopes generated by the first neutron capture. This paper comprises calculations for plutonium/minor actinides/thorium fuel compositions and their correlated final burn-up for a generic pebble bed HTR based on the reference design of the 400 MW PBMR. In particular the cross sections and the neutron balance of the different minor actinide isotopes in the higher thermal energy spectrum of a HTR will be discussed. For a fuel mixture of plutonium and minor actinides a significant burn-up of these actinides up to 20% can be achieved but at the expense of a higher residual fraction of plutonium in the burned fuel.

Burning or transmutation of minor actinides (MA: Np, Am, Cm) that are classified as the high-level radioactive waste in the current nuclear fuel cycle is an option for the advanced nuclear fuel cycle. Although the thermochemical and thermophysical properties of minor actinide compounds are essential for the design of MA-bearing fuels and analysis of their behavior, the experimental data on minor actinide compounds are limited. To support the research and development of the MA-bearing fuels, the property measurements were carried out on minor actinide nitrides and oxides. The lattice parameters and their thermal expansions were measured by high-temperature X-ray diffractometry. The specific heat capacities were measured by drop calorimetry and the thermal diffusivities by laser-flash method. The thermal conductivities were determined by the specific heat capacities, thermal diffusivities and densities. The oxygen potentials were measured by electromotive force method.

This study reports on an effort to stop the illegal sale of cigarettes to minors. In Santa Clara County, Calif, 412 stores and 30 vending machines were visited by 18 minors aged 14 through 16 years with the intent to purchase cigarettes; they were successful at 74% of the stores and 100% of the vending machines. After an aggressive six-month campaign using communitywide media, direct merchant education, contact with the chief executive officers of chain stores and franchise operations owned by major companies, and grassroots work with community organizations, the percentage of stores with illegal over-the-counter sale of cigarettes to minors was reduced to 39%. Sales from vending machines were not reduced. While much remains to be accomplished in stopping the illegal sale of tobacco to minors, data from this study illustrate that a well-designed community and merchant education campaign can significantly reduce such sales.

Contested minorities – the case of Upper Silesia

Directory of Open Access Journals (Sweden)

Gierczak Dariusz

2015-06-01

Full Text Available Upper Silesia in terms of ethnicity is a typical example of a historical region in Europe, but in fact, one of the few exceptions in contemporary Poland, where its mixed ethnic and religious structures have at least partly survived until today. While their existence had been denied by Nazi Germany (1933-1945 as well as by the Polish People's Republic (1945-1989, the emancipation of the German and Silesian minorities after the democratic changes of 1989 have evoked strong emotions in the ethnically almost uniform country. Nonetheless, the recent situation of minorities has improved as never before. Minority organisations has been officially recognized and German finally has become the second language in some municipalities of Upper Silesia, but the largest ethnic group in the whole country, the Silesians, have still experienced no formal recognition as a national minority. This article deals with the demographic aspects of the ethnic groups in Upper Silesia since the 19th century until recent times. The census results concerning the ethnic minorities or languages in Upper Silesia have been contested since the first records of that kind have been taken. The outcomes of the both last censuses of 2002 and 2011 concerning the minority question reflected for the first time a much more realistic picture of the status quo. Furthermore, they showed that the idea of Silesian identification found an unexpected high number of supporters. This fact indicates an emerging meaning of regional identification amid significant changes of cultural values in Polish society.

Socio-legal protection of minorities -- a study of Indian educational cases.

Science.gov (United States)

Chandra, S

1992-01-01

Many Muslim families do not enroll their children in school. This is so because material in school syllabi sometimes goes against Islamic beliefs or adversely affects the Muslim self-image, orthodox parents will not send their daughters to coeducational academic institutions, some adults do not realize the benefits of education with regard to the welfare of their children, and many Muslim localities remain resource-deficient slums. The government, local authorities, and Muslims should band together to encourage and enable backward Muslim minorities to uplift themselves academically. Steps to that end could include adding minority representation to the bodies which approve the syllabi in order to monitor the potential inclusion of offensive material, continuing to upgrade teachers in Muslim schools, optimizing available space in Muslim educational institutions, empowering minorities commissions in states to help backward minorities to garner education, eliminating the rules of discretion to avoid corruption and nepotism, simplifying the rules and procedures governing grants to educational institutions, conducting a scientific survey to obtain accurate baseline information for use in planning the education of Muslim minorities, giving special preference to localities populated predominantly with minorities when establishing educational institutions, and providing scholarship to bright and needy minority students. Additionally, the National Minorities Commission should be empowered by the central government to collect information and report on the educational, social, and economic conditions of minorities across the country. Autonomy in management must also be respected, with regulatory measures applicable to minority institutions being reasonable and appropriate.

Impact of minor actinide recycling on sustainable fuel cycle options

Energy Technology Data Exchange (ETDEWEB)

Heidet, F.; Kim, T. K.; Taiwo, T. A.

2017-11-01

The recent Evaluation and Screening study chartered by the U.S. Department of Energy, Office of Nuclear Energy, has identified four fuel cycle options as being the most promising. Among these four options, the two single-stage fuel cycles rely on a fast reactor and are differing in the fact that in one case only uranium and plutonium are recycled while in the other case minor actinides are also recycled. The two other fuel cycles are two-stage and rely on both fast and thermal reactors. They also differ in the fact that in one case only uranium and plutonium are recycled while in the other case minor actinides are also recycled. The current study assesses the impact of recycling minor actinides on the reactor core design, its performance characteristics, and the characteristics of the recycled material and waste material. The recycling of minor actinides is found not to affect the reactor core performance, as long as the same cycle length, core layout and specific power are being used. One notable difference is that the required transuranics (TRU) content is slightly increased when minor actinides are recycled. The mass flows are mostly unchanged given a same specific power and cycle length. Although the material mass flows and reactor performance characteristics are hardly affected by recycling minor actinides, some differences are observed in the waste characteristics between the two fuel cycles considered. The absence of minor actinides in the waste results in a different buildup of decay products, and in somewhat different behaviors depending on the characteristic and time frame considered. Recycling of minor actinides is found to result in a reduction of the waste characteristics ranging from 10% to 90%. These results are consistent with previous studies in this domain and depending on the time frame considered, packaging conditions, repository site, repository strategy, the differences observed in the waste characteristics could be beneficial and help improve

Partitioning and Transmutation of minor actinides

International Nuclear Information System (INIS)

Koch, L.; Wellum, R.

1991-01-01

The partitioning of minor actinides from spent fuels and their transmutation into short-lived fission products has been the topic of two dedicated meetings organized jointly by the European Commission and the OECD. The conclusion of the last meeting in 1980, in short, was that partitioning and transmutation of minor actinides, especially in fast reactors, seemed possible. However, the incentive, which would be a reduction of the radiological hazard to the public, was too small if long-lived fission products were not included. Furthermore this meeting showed that minor actinide targets or possible nuclear fuels containing minor actinides for transmutation had not yet been developed. The European Institute for Transuranium Elements took up this task and has carried it out as a small activity for several years. Interests expressed recently by an expert meeting of the OECD/NEA (Paris, 25 April 1989), which was initiated by the proposed Japanese project Omega, led us to the conclusion that the present state of knowledge should be looked at in a workshop environment. Since the Japanese proposal within the project Omega is based on a broader approach we needed this evaluation to assess the relevance of our present activity and wanted to identifiy additional studies which might be needed to cover possible future demands from the public. This workshop was therefore organized, and participants active in the field from EC countries, the USA and Japan were invited

For the past 20 years, the percentage of the American population consisting of nonwhite minorities has been steadily increasing. By 2050, these nonwhite minorities, taken together, are expected to become the majority. Meanwhile, despite almost 50 years of efforts to increase the representation of minorities in the healthcare professions, such representation remains grossly deficient. Among the underrepresented minorities are African and Hispanic Americans; Native Americans, Alaskans, and Pacific Islanders (including Hawaiians); and certain Asians (including Hmong, Vietnamese, and Cambodians). The underrepresentation of underrepresented minorities in the healthcare professions has a profoundly negative effect on public health, including serious racial and ethnic health disparities. These can be reduced only by increased recruitment and development of both underrepresented minority medical students and underrepresented minority medical school administrators and faculty. Underrepresented minority faculty development is deterred by barriers resulting from years of systematic segregation, discrimination, tradition, culture, and elitism in academic medicine. If these barriers can be overcome, the rewards will be great: improvements in public health, an expansion of the contemporary medical research agenda, and improvements in the teaching of both underrepresented minority and non-underrepresented minority students.

Patterns of Mental Health Care Utilization Among Sexual Orientation Minority Groups.

Science.gov (United States)

Platt, Lisa F; Wolf, Julia Kay; Scheitle, Christopher P

2018-01-01

Prior studies of the utilization of mental health professionals by sexual minority populations have relied on data that are now dated or not nationally representative. These studies have also provided mixed findings regarding gender differences in the utilization of mental health professionals among sexual minority individuals. Using data from the 2013-2015 National Health Interview Surveys, this study investigates (1) how sexual minority individuals compare to heterosexual participants in their utilization of mental health professionals; and (2) gender differences in that utilization. The results indicate sexual minority individuals utilize mental health care professionals at higher rates than heterosexual individuals even after controlling for measures of mental health and other demographic characteristics; this is true for both men and women. However, gender moderates the sexual minority effect on utilization rates. Sexual minority men utilize mental health professionals at a high rate, such that their utilization rates are similar to sexual minority women, contrary to the gender gap seen among heterosexuals.

Sexual Minority Status, Peer Harassment, and Adolescent Depression

Science.gov (United States)

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

2013-10-01

The links of minority stressors (workplace discrimination, expectations of stigma, internalized heterosexism, and identity management strategies) with psychological distress and job satisfaction were examined in a sample of 326 sexual minority employees. Drawing from minority stress theory and the literature on the vocational experiences of sexual minority people, patterns of mediation and moderation were tested. Minority stressors were associated with greater distress and lower job satisfaction. A mediation model was supported in which the links of discrimination and internalized heterosexism with psychological distress were mediated by a concealment-focused identity management strategy (i.e., avoiding), and the links of discrimination, expectations of stigma, and internalized heterosexism with job satisfaction were mediated by a disclosure-focused identity management strategy (i.e., integrating). Tests of moderation indicated that for sexual minority women (but not men), the positive association of discrimination with distress was stronger at higher levels of internalized heterosexism than at lower levels. In addition, lower levels of internalized heterosexism and concealment strategies (i.e., counterfeiting and avoiding) and higher levels of a disclosure strategy (i.e., integrating) were associated with higher job satisfaction in the context of low discrimination, but this buffering effect disappeared as level of discrimination increased. The implications of these findings for minority stress research are discussed, and clinical recommendations are made.

Sexual minorities face greater exposure to discrimination and rejection than heterosexuals. Given these threats, sexual minorities may engage in sexual orientation concealment in order to avoid danger. This social stigma and minority stress places sexual minorities at risk for anxiety and related disorders. Given that three fourths of anxiety disorder onset occurs before the age of 24, the current study investigated the symptoms of generalized anxiety disorder, social phobia, panic disorder, posttraumatic stress disorder, and depression in sexual minority young adults relative to their heterosexual peers. Secondarily, the study investigated sexual orientation concealment as a predictor of anxiety and related disorders. A sample of 157 sexual minority and 157 heterosexual young adults matched on age and gender completed self-report measures of the aforementioned disorders, and indicated their level of sexual orientation concealment. Results revealed that sexual minority young adults reported greater symptoms relative to heterosexuals across all outcome measures. There were no interactions between sexual minority status and gender, however, women had higher symptoms across all disorders. Sexual minority young women appeared to be at the most risk for clinical levels of anxiety and related disorders. In addition, concealment of sexual orientation significantly predicted symptoms of social phobia. Implications are offered for the cognitive and behavioral treatment of anxiety and related disorders in this population. Copyright © 2015. Published by Elsevier Ltd.

Minor crashes and 'whiplash' in the United States.

Science.gov (United States)

Bartsch, Adam J; Gilbertson, Lars G; Prakash, Vikas; Morr, Douglas R; Wiechel, John F

2008-10-01

In the United States there is currently a paucity of available real world minor rear crash data with struck vehicle delta-V, or speed change, less than or equal to 15 kilometers per hour. These data are essential as researchers attempt to define 'whiplash' injury risk potential in these minor crashes. This study analyzed a new set of 105 U.S. minor rear aligned crashes between passenger vehicles. Mean struck vehicle delta-V and acceleration were 6.3 km/h (s.d. = 2.1 km/h) and 1.4 g (s.d. = 0.5 g), respectively. A total of 113 struck vehicle occupants were diagnosed within five weeks post-crash with 761 ICD-9-CM complaints and 427 AIS injuries (99.5% AIS1) attributed to the crashes. No striking vehicle occupants reported complaints. The main ICD-9-CM diagnoses were 40.6% cervical, 22.5% lumbar/sacral and 10.2% thoracic and the main AIS1 diagnoses were 29.7% cervical, 23.2% lumbar/sacral and 14.3% thoracic. The diagnosis disparity was mainly due to coding for pre-existing degenerative diagnosis in ICD-9-CM. Degenerative spine conditions were not significant for increased AIS1 injury risk. Surprisingly, many non-'whiplash' diagnoses were found. The AIS injury diagnosis distribution and frequency in these minor delta-V crashes did not correspond with previous minor rear crash studies. A prospectively collected and unbiased minor rear crash databank in the model of CIREN or NASS is highly desirable to verify or refute these results for the U.S. population since the current study cohort may have been influenced by litigation.

Sex Offenses Against Minors in China: An Empirical Comparison.

Science.gov (United States)

Hu, Ming; Liang, Bin; Huang, Siwen

2017-08-01

In recent years, due to a number of notorious sex offense cases against minors, a new punitive public attitude emerged in China and pressed for harsher crackdown and punishment against sex offenders. In particular, an "engagement in prostitution with a minor" law (Article 360 of the Criminal Law) was targeted as "unjust" based on the belief that offenders of such crimes often received "lenient" punishment, and many called for its abolition. In this study, based on 440 adjudicated sex offense cases, we examine potential differences across three sex offenses (including rape, child molestation, and engagement in prostitution with a minor) in the demographics of defendants and victims, offending characteristics, and trials and sentences of convicted offenders. Our empirical inquiry pointed to the unique nature of engagement in prostitution with a minor. Offenders of such crimes seemingly carried a different profile, compared with offenders of the other two sex crimes. Moreover, our data casted some doubt on the "lenient" punishment received by offenders of engagement in prostitution with a minor. Policy implications were also drawn based on our findings.

1996-07-01

The question of education in India cannot be properly discussed without referring to its socio-linguistic context. This paper provides background information on the linguistic profile of India. The term "minorities" in the Indian context is defined, and the protection offered to linguistic minorities in the Indian Constitution is examined. A discussion of language policy in Indian education follows in which the recommendations of the different education commissions are analysed. The important issues covered include: the number of languages that are taught, the medium of instruction, and the educational policies regarding speakers of minority languages. The article also discusses different language movements and their impact on Indian education.

2014-01-01

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.

Discrimination, Mental Health, and Substance Use Disorders Among Sexual Minority Populations.

Lee, Ji Hyun; Gamarel, Kristi E; Bryant, Kendall J; Zaller, Nickolas D; Operario, Don

2016-08-01

Sexual minority (lesbian, gay, bisexual) populations have a higher prevalence of mental health and substance use disorders compared to their heterosexual counterparts. Such disparities have been attributed, in part, to minority stressors, including distal stressors such as discrimination. However, few studies have examined associations between discrimination, mental health, and substance use disorders by gender among sexual minority populations. We analyzed data from 577 adult men and women who self-identified as lesbian, gay, or bisexual and participated in Wave 2 of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC). Six questions assessed discrimination due to sexual orientation. Weighted multivariable logistic regression examined associations between experiences of sexual orientation discrimination and both mental health and substance use disorders. Analyses were conducted separately for sexual minority men and women, adjusting for sociodemographic covariates. Sexual minority men who ever experienced discrimination (57.4%) reported higher odds of any lifetime drug use disorder and cannabis use disorder compared to sexual minority men who never experienced discrimination. Sexual minority women who ever experienced discrimination (42.9%) reported higher odds of any lifetime mood disorder and any lifetime anxiety disorder compared to sexual minority women who never experienced discrimination. The findings suggest that discrimination is differentially associated with internalizing (mental health) and externalizing (substance use) disorders for sexual minority men and women. These findings indicate a need to consider how homophobia and heteronormative discrimination may contribute to distinct health outcomes for lesbian and bisexual women compared with gay and bisexual men.

2014-04-01

The study of disparities in minority recruitment to cancer clinical trials has focused primarily on inquiries among minority populations. Yet very little is known about the perceptions of individuals actively involved in minority recruitment to clinical trials within cancer centers. Therefore, the authors assessed the perspectives of cancer center clinical and research personnel on barriers and facilitators to minority recruitment. In total, 91 qualitative interviews were conducted at 5 US cancer centers among 4 stakeholder groups: cancer center leaders, principal investigators, research staff, and referring clinicians. All interviews were recorded and transcribed. Qualitative analyses of response data was focused on identifying prominent themes related to barriers and facilitators to minority recruitment. The perspectives of the 4 stakeholder groups were largely overlapping with some variations based on their unique roles in minority recruitment. Four prominent themes were identified: 1) racial and ethnic minorities are influenced by varying degrees of skepticism related to trial participation, 2) potential minority participants often face multilevel barriers that preclude them from being offered an opportunity to participate in a clinical trial, 3) facilitators at both the institutional and participant level potentially encourage minority recruitment, and 4) variation between internal and external trial referral procedures may limit clinical trial opportunities for racial and ethnic minorities. Multilevel approaches are needed to address barriers and optimize facilitators within cancer centers to enhance minority recruitment for cancer clinical trials. © 2014 American Cancer Society.

The Yugoslav Minority Standards and Croats in the FR of Yugoslavia

Directory of Open Access Journals (Sweden)

Milenko Horvatić

2001-06-01

Full Text Available Ethnic relations and the treatment of minorities have proven themselves to be an exceptionally important issue for security and stability in the Balkans, especially in the Federal Republic of Yugoslavia (FRY. The perspective for peace in this country is to a great deal dependent on the ability to find a solution to the problems of national minorities. All Yugoslav constitutions have included clauses relating to minority rights, yet significant differences were evident in the degrees of stipulated protection for minorities. In these acts minority status was regulated as a liberty and a right enjoyed by individuals − members of minorities. The status of a minority as a collective group was generally not regulated, and the measures for the protection of collective rights were not sufficiently developed. Nevertheless, guarantees in the Constitution of the FRY and the fact that international accords in the Yugoslav legal system stand above the law, on the whole provide a good basis for developing a system of protection of minority rights. Croats live on the territory of the present FRY as an indigenous and homogeneous group in the republics of Serbia and Montenegro. In Serbia the largest Croat concentration is located in the Autonomous Province of Vojvodina. Following the Kosovo crisis, no Croats remained in Kosovo. In Montenegro Croats live mostly in Boka Kotorska. Minorities make up a third of the population of the FRY and the largest minority groups live in Serbia. Based on an analysis of census figures after WWII (the period examined it is apparent that the number and percentage of minority group members has been on a continuous decline, except in the case of the Albanians, Roma and Yugoslavs. The national (ethnic structure of the FRY has significantly changed since the 1991 census, to the detriment of the percentage of minority populations in the overall population. Taking into consideration the period from 1961 to the (most recent 1991 census

As a private, non-state-owned teaching hospital adjacent to a predominately low income African American community in Baltimore, the University of Maryland Medical System (hereafter called the Medical System) in partnership with the state's medical school has historically provided excellent medical care to the community's residents regardless of their ability to pay. Nevertheless, executive leadership recognized that the Medical System needed to be even more socially and economically responsible to the minority community by investing more of the system's resources in that community. Doing so would improve the economic strength of the community, and this strength would help the Medical System to continue to thrive and expand its business in Baltimore City. Therefore, in the late 1980s, the Medical System created a program that focuses on greater inclusion of minorities particularly African Americans, in personnel, construction, purchasing, and community outreach. In the area of personnel, recruitment efforts have focused on increasing the representation of minorities, particularly African Americans, in management and residency positions. The result has been the creation of a more supportive environment for minority personnel throughout the organization as well as for minority patients and vendors who have dealings with the medical system. In the area of construction, minority development efforts have included the establishment of a flexible bid-award policy and a partnership with the minority business community. As a result, total construction dollars spent with minority-owned firms increased from $2 million to $18 million over seven years, and the portion of these dollars spent with African American-owned firms increased sixfold. In the area of purchased goods and services, more creative approaches to improving minority participation have been necessary. These have included partnering minority distributors with major suppliers and literally assisting in the creation

Traffic mortality and the role of minor roads.

van Langevelde, Frank; van Dooremalen, Coby; Jaarsma, Catharinus F

2009-01-01

Roads have large impacts on wildlife, as they form one of the principal causes of mortality, and disturbance and fragmentation of habitat. These impacts are mainly studied and mitigated on major roads. It is, however, a widespread misconception that most animals are killed on major roads. In this paper, we argue that minor roads have a larger impact on wildlife with respect to habitat destruction, noise load and traffic mortality. We use data on traffic related deaths in badgers (Meles meles) in The Netherlands to illustrate that traffic mortality is higher on minor roads. We ask for a more extensive investigation of the environmental impacts of minor roads. Moreover, we argue that the success of mitigation on roads drastically increases when both major and minor roads are integrated in the planning of traffic flows. Therefore, we propose a strategy based on the concept of a "traffic-calmed area". Traffic-calmed areas create opportunities for wildlife by decreasing limitations for animal movement. We ask for further studies to estimate what size traffic-calmed areas should be to maintain minimum viable animal populations.

Evolutionary Analysis of Minor Histocompatibility Genes In Hydra

KAUST Repository

Aalismail, Nojood

2016-01-01

In the present study we took initiative to study the self/nonself recognition in hydra and its relation to the immune response. Moreover, performing phylogenetic analysis to look for annotated immune genes in hydra gave us a potential to analyze the expression of minor histocompatibility genes that have been shown to play a major role in grafting and transplantation in mammals. Here we obtained the cDNA library that shows expression of minor histocompatibility genes and confirmed that the annotated sequences in databases are actually present. In addition, grafting experiments suggested, although still preliminary, that homograft showed less rejection response than in heterograft. Involvement of possible minor histocompatibility gene orthologous in immune response was examined by qPCR.

Minority Political Representation: Muslim Councilors in Newham and Hackney

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.

Clinical research involving minors in international and serbian regulations.

Planojević, Nina; Zivojinović, Dragica

2013-07-01

Participation in clinical trials can be useful for the health of a person, in who it is conducted, but it does not have to be - it can even be harmful. Therefore, primary motive to accept such risk is humanity and human wish to contribute to the progress of medicine; this is expressed by personal consent. The consent, however, can be an expression of personal humanity, and for this, it is not logical that someone can give consent on behalf of someone else, as it is done by a legally authorized representative on behalf of a minor. Therefore, authors raise 3 questions: What are the reasons to consider representative's consent acceptable? How should a model of regulations look like in order to provide the most complete possible protection to a minor? Is actual regulation of minors' position within international and Serbian law, analyzed here by authors for their specific solutions, acceptable? Representative's consent is acceptable only for therapeutic research, because these can bring benefits to everyone's health, including a minor in which those are conducted - this is an acceptable (secondary) motive of participation in the research. Expression of humanity on other's behalf, typical for non-therapeutic research, is not acceptable; this makes ban of minors' participation in non-therapeutic research more appropriate regulation model. International regulations are not in accordance to results presented in the paper for allowing participation of minors both in therapeutic and non-therapeutic research. Serbian regulation is closer to the most acceptable regulation model.

Full Text Available The public service, which should be the guardian of the identity of national minorities, fell under the political pressure. In this way, it came out of the scope of its actions. Leading people in independent media believe that the role of the public service is crucial in protecting national minorities.But the media can not do it alone. First of all, the state must regulate, and respect what it has brought. With strong strategies and the inclusion of national minorities in all social trends, it is possible to achieve, not fully, but partially, the equality of all those who liveon the territory of BiH.On the other hand, the public service must respect what the state says. The Communications Regulatory Agency is obliged to impose rules in an adequate manner and at the same time to monitor how much the media (public service meets its obligations.

Twenty Years of National Minority Protection in the Republic of Croatia

Directory of Open Access Journals (Sweden)

Siniša Tatalović

2011-12-01

Full Text Available The paper contains a review of policies towards national minorities in the Republic of Croatia in the past twenty years, with reference to the perspective of minority rights implementation. The topic has been analysed in relation to two independent variables – the influence of external factors, i.e. the international community, and internal political processes that have had influence on the realisation of national minority rights. Today, as a country and society on the eve of accession to the European Union, along with a legislatively developed and institutionally branched model of the implementation of national minority rights, we can not claim to have established permanent protection of their rights. The degree of national minority integration in society is the only true indicator of policy success in relation to national minorities. The goal of this policy ought to be complete integration of national minorities into public, cultural, economic and political life, but accompanied by the preservation of their cultural and national identity. The Croatian model has been set up in such a way, but the manner in which it functions will depend on the political will to implement it, the willingness of national minority members to be active subjects of social and political life, as well as on civil society and Croatian society as a whole.

Pesticides are frequently detected in water bodies due to the agricultural application, which may pose impacts on aquatic organisms. The enantioselective bioaccumulation and metabolism of the herbicide lactofen in aquatic floating macrophyte Lemna minor (L. minor) were studied and the potential L. minor phytoremediation was investigated. Ultra-high performance liquid chromatography - tandem mass spectrometry (UHPLC-MS-MS) analysis for lactofen and its two known metabolites in L. minor was performed. The initial concentrations of racemic lactofen, R-lactofen and S-lactofen were all 30μgL -1 in the growth solution. The distribution of lactofen and its metabolites in growth solution and L. minor was determined throughout a 5-d laboratory trial. It was observed that S-lactofen was preferentially taken up and metabolized in L. minor. After rac-lactofen exposure, the accumulation amount of S-lactofen was approximately 3-fold more than that of R-lactofen in L. minor and the metabolism rate of S-lactofen (T 1/2 =0.92 d) was significantly faster than R-lactofen (T 1/2 =1.55 d). L. minor could only slightly accelerate the metabolism and removal of lactofen in the growth solution. As for the metabolites, desethyl lactofen was found to be the major metabolite in L. minor and the growth solution, whereas the metabolite acifluorfene was undetectable. No interconversion of the two enantiomers was observed after individual enantiomer exposure, indicating they were configurationally stable. The findings of this work represented that the accumulation and metabolism of lactofen in L. minor were enantioselective, and L. minor had limited capacity for the removal of lactofen and its metabolite in water.

Advances in lesbian, gay, and bisexual (sexual minority [SM]) acceptance and equality have been made in the past decade. However, certain SM subgroups continue to be disadvantaged due to lack of data and, thus, lack of knowledge about these populations. Data for older sexual minorities are especially lacking and will be increasingly important as more sexual minorities enter older age. This research explores results from a nationally representative health survey to elucidate some health indicators for older sexual minorities. Data from the 2013 and 2014 National Health Interview Surveys (NHIS) were pooled for increased sample size, and established research methods were followed as recommended by prior NHIS sexual orientation studies. We conducted descriptive analyses on the differences between SM and heterosexual groups, aged 65 years and older, for 12 health indicators. Four out of the 12 health indicators were significantly different for sexual minorities, and three out of those four indicated positive health outcomes or behaviors when compared with heterosexuals. Sexual minorities were more than three times as likely to receive HIV testing as heterosexual peers. Sexual minorities were more likely to receive an influenza vaccination, and much more likely to report excellent or very good health, than their heterosexual peers. Sexual minorities were more than twice as likely to report binge drinking, which is consistent with prior research for adult sexual minorities. This analysis is the first to examine national data on health indicators for sexual minorities, aged 65 years and older, using NHIS data. As more surveys begin to collect SMdata and more years of data are collected by NHIS, a clearer picture of the health of older adult sexual minorities should emerge.

Peer harassment and risky behavior among sexual minority girls and boys.

Martin-Storey, Alexa; Crosnoe, Robert

2014-01-01

The role of peer harassment in the association between sexual minority status and adolescent risky behavior was examined for 15-year-olds in the NICHD Study of Early Child Care and Youth Development (n = 957). The findings, although exploratory, suggest the importance of gender. For girls, peer harassment was best viewed as a moderator of the link between sexual minority status and increased risky behavior. It intensified an existing association, reflecting the gendered nature of the impact of sexual minority status on the adolescent social context. For boys, peer harassment was primarily a mediator, such that sexual minority status was associated with more risky behavior via elevated harassment, although sexual minority status itself was associated with lower risky behavior overall.

Cancer does not occur in all ethnic and racial groups at similar rates. In addition, responses to treatment also vary in certain ethnic and racial groups. For Hispanics, the overall cancer incidence is generally lower yet for some specific tumor types, the incidence rates are higher compared to other populations. Although disparities are recognized for treatment outcomes and prevention methodologies for Hispanics and other minority populations, specific recruiting and reporting of minorities remains a challenge. In order to circumvent this problem, the Cancer Therapy and Research Center (CTRC) has developed a new minority recruitment plan for all cancer related clinical trials at this Institute. The overall goal of this initiative is to increase the accrual of minorities in cancer clinical trials by implementing several key interventions. The Cancer Therapy & Research Center (CTRC) at the University of Texas Health Science Center at San Antonio established the Clinical Trials Accrual Task Force to develop and monitor interventions designed to increase accrual to cancer clinical trials, specifically the accrual of minorities with a focus on the Hispanic population that makes up 68% of the CTRC's catchment area. A Minority Accrual Plan (MAP) was implemented in March 2013 as part of the process for initiating and conducting cancer-related clinical trials at the CTRC. The Minority Accrual Plan focuses on Hispanic enrollment due to the characteristics of the South Texas population served by the CTRC but could be easily adapted to other populations. The CTRC has designed a process to prospectively address the challenge of deliberately enrolling minority subjects and accurately accounting for the results by implementing a Minority Accrual Plan for every cancer-related clinical trial at CTRC.

With the advent of time-dependent thrombolytic therapy for ischemic stroke, it has become increasingly important to differentiate transient ischemic attack (TIA) from minor stroke patients after symptom onset quickly. This study investigated the difference between TIA and minor stroke based on age, blood pressure, clinical features, duration of TIA, presence of diabetes, ABCD² score, digital subtraction angiography (DSA) and blood lipids. One hundred seventy-one patients with clinical manifestations as transient neurological deficits in Nanjing Drum Tower Hospital were studied retrospectively. All patients were evaluated by ABCD² score, blood lipid test, fibrinogen, and Holter electrocardiograph and DSA on admission. Patients were categorized into TIA group or minor stroke group according to CT and MRI scan 24 h within symptom onset. The study suggested that minor stroke patients were more likely to have a higher ABCD² score (odds ratio (OR) 2.060; 95% confidence interval (CI) 1.293-3.264). Receiver-operating characteristic curves identified ABCD² score >4 as the optimal cut-off for minor stroke diagnosis. Total serum cholesterol seemed a better diagnostic indicator to discriminate minor stroke from TIA (OR 4.815; 95% CI 0.946-1.654) than other blood lipids in simple logistic regression, but not valuable for the differentiation between TIA and minor stroke in multivariate logistic regression. Higher severity of intracranial internal carotid stenosis, especially >90%, were more likely to have minor stroke, but was not a reliable diagnostic indicator (P > 0.05). ABCD² could help clinicians to differentiate possible TIA from minor stroke at hospital admission while blood lipid parameters and artery stenosis location offer limited help.

Adolescent brain development and the mature minor doctrine.

Science.gov (United States)

Silber, Tomas J

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.

Full Text Available The breakdown of the former Yugoslavia has resulted in formation of new independent states while the former co-citizens and constitutive people have found themselves in new roles. Some have become a majority while some have become a minority, with an aspiration to affirm the status in the public sphere. As a country with a large numbers of immigrants from the former Yugoslavia, Slovenia is facing a challenge of the confirmation of ethnic pluralism within its borders, along with solutions and appropriate places for 'new' minorities (the usual appellation for ethnic groups formed by the members of the former Yugoslavia, where the Serbs are outnumbering the rest. At the same time, the new minorities face a challenge of constitution foundation of their own associations, that is, formation of their own identity and public affirmation in the new context. This paper discusses these ongoing processes with a special attention to the Serbian ethnic group.

Congress awarded $156 million to deal with the HIV epidemic among African-Americans and other minorities. AIDS service providers welcomed the money but said that much more needs to be done. Community-based organizations (CBOs) serving minority populations are relatively new, and many need improved accounting and auditing procedures, information technology, and leadership development systems if they are to be productive. Hurdles faced by CBOs include competing for funding, recruiting volunteers, educating minority physicians, and planning community responses. The opinions of two former U.S. Surgeon Generals regarding this new funding and how it should be used are discussed.

Status of National Minorities in Developed European Countries

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.

[Is it necessary to control the population growth of national minorities].

Science.gov (United States)

Tian, X Y

1981-02-01

In the process of Socialist construction and modernization, the development of the population of national minorities deserves our attention because it is directly related to the economic and cultural development in the areas inhabited by such national minorities, and it has a great impact on the welfare and future of those people. Moreover, the population growth of the minorities is a key factor in the national population control strategy. A rapid population growth among the minorities has caused serious problems in distribution of farm land and food supply, low personal income, a rise in the unemployment rate, and a rise in the illiteracy rate. This has prevented a rise in the living standard among the minority population. In order to prevent and solve population problems among the minorities, we must take appropriate measures according to local conditions to control population increases. Through popularization of education, population growth may be put under control. For those people who volunteer to practice family planning, the government should provide all kinds of assistance. At the same time, an effort is needed to introduce the necessity of improving birth quality, to popularize new methods of child birth, and to develop health and medical care for the general public, so that the quality of the minority population may be gradually improved.

Minors and euthanasia: a systematic review of argument-based ethics literature.

Science.gov (United States)

Cuman, Giulia; Gastmans, Chris

2017-07-01

Euthanasia was first legalised in the Netherlands in 2002, followed by similar legislation in Belgium the same year. Since the beginning, however, only the Netherlands included the possibility for minors older than 12 years to request euthanasia. In 2014, the Belgian Act legalising euthanasia was amended to include requests by minors who possess the capacity of discernment. This amendment sparked great debate, and raised difficult ethical questions about when and how a minor can be deemed competent. We conducted a systematic review of argument-based literature on euthanasia in minors. The search process followed PRISMA guidelines. Thirteen publications were included. The four-principle approach of medical ethics was used to organise the ethical arguments underlying this debate. The justification for allowing euthanasia in minors is buttressed mostly by the principles of beneficence and respect for autonomy. Somewhat paradoxically, both principles are also used in the literature to argue against the extension of legislation to minors. Opponents of euthanasia generally rely on the principle of non-maleficence. The present analysis reveals that the debate surrounding euthanasia in minors is at an early stage. In order to allow a more in-depth ethical discussion, we suggest enriching the four-principle approach by including a care-ethics approach. What is Known: • The Netherlands and Belgium are the only two countries in the world with euthanasia legislation making it possible for minors to receive euthanasia. • This legislation provoked great debate globally, with ethical arguments for and against this legislation. What is New: • A systematic description of the ethical concepts and arguments grounding the debate on euthanasia in minors, as reported in the argument-based ethics literature. • A need has been identified to enrich the debate with a care-ethics approach to avoid oversimplifying the ethical decision-making process.

Full Text Available 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.

Purpose of review This review summarized trends and key findings from empirical studies conducted between 2011–2017 regarding eating disorders and disordered weight and shape control behaviors among lesbian, gay, bisexual, and other sexual minority (i.e., non-heterosexual) populations. Recent findings Recent research has examined disparities through sociocultural and minority stress approaches. Sexual minorities continue to demonstrate higher rates of disordered eating; disparities are more pronounced among males. Emerging data indicates elevated risk for disordered eating pathology among sexual minorities who are transgender or ethnic minorities. Dissonance-based eating disorder prevention programs may hold promise for sexual minority males. Summary Continued research must examine the intersections of sexual orientation, gender, and ethnic identities, given emergent data that eating disorder risk may be most prominent among specific subgroups. More research is needed within sexual minorities across the lifespan. There are still a lack of eating disorder treatment and prevention studies for sexual minorities. PMID:28660475

Discrimination, Mental Health, and Substance Use Disorders Among Sexual Minority Populations

OpenAIRE

Lee, Ji Hyun; Gamarel, Kristi E.; Bryant, Kendall J.; Zaller, Nickolas D.; Operario, Don

2016-01-01

Purpose: Sexual minority (lesbian, gay, bisexual) populations have a higher prevalence of mental health and substance use disorders compared to their heterosexual counterparts. Such disparities have been attributed, in part, to minority stressors, including distal stressors such as discrimination. However, few studies have examined associations between discrimination, mental health, and substance use disorders by gender among sexual minority populations.

"I AM a Man": Manhood, Minority Men's Health and Health Equity.

Science.gov (United States)

Griffith, Derek M

2015-08-07

To consider how manhood is a key social determinant of minority men's health. This commentary explicates how manhood intersects with other determinants of health to shape minority men's stress responses, health behaviors and health outcomes across the life course. Manhood, which perpetually needs to be proven, is an aspirational identity that is defined by the intersection of age, race/ethnicity and other identities. Minority men seek to and successfully embody US-cultural and ethnic-specific aspects of manhood in their daily lives by engaging in behaviors that constantly reaffirm their gender identity through a complex internal and social calculus that varies by intra-personal characteristics and context. Manhood and health are relational constructs that highlight how the salience of masculinities are shaped by perceived and actual social norms and expectations. A life course perspective adds a framework for considering how some gendered beliefs, goals and behaviors change over time while others remain static. Three life course frameworks highlight different mechanisms through which minority men's life experiences and physiological and behavioral responses to gendered social norms, beliefs and expectations become embodied as premature mortality and other health outcomes over the life course. Manhood represents an important lens to understand how minority men's identities, goals and priorities affect their health, yet the role of manhood in minority men's health is understudied and underdeveloped. To achieve health equity, it is critical to consider how manhood shapes minority men's lives and health across the life course, and to address how manhood affects gendered and non-gendered mechanisms and pathways that explain minority men's health over time.

Minor Crashes and ‘Whiplash’ in the United States

Science.gov (United States)

Bartsch, Adam J.; Gilbertson, Lars G.; Prakash, Vikas; Morr, Douglas R.; Wiechel, John F.

2008-01-01

In the United States there is currently a paucity of available real world minor rear crash data with struck vehicle delta-V, or speed change, less than or equal to 15 kilometers per hour. These data are essential as researchers attempt to define ‘whiplash’ injury risk potential in these minor crashes. This study analyzed a new set of 105 U.S. minor rear aligned crashes between passenger vehicles. Mean struck vehicle delta-V and acceleration were 6.3 km/h (s.d. = 2.1 km/h) and 1.4g (s.d. = 0.5g), respectively. A total of 113 struck vehicle occupants were diagnosed within five weeks post-crash with 761 ICD-9-CM complaints and 427 AIS injuries (99.5% AIS1) attributed to the crashes. No striking vehicle occupants reported complaints. The main ICD-9-CM diagnoses were 40.6% cervical, 22.5% lumbar/sacral and 10.2% thoracic and the main AIS1 diagnoses were 29.7% cervical, 23.2% lumbar/sacral and 14.3% thoracic. The diagnosis disparity was mainly due to coding for pre-existing degenerative diagnosis in ICD-9-CM. Degenerative spine conditions were not significant for increased AIS1 injury risk. Surprisingly, many non-‘whiplash’ diagnoses were found. The AIS injury diagnosis distribution and frequency in these minor delta-V crashes did not correspond with previous minor rear crash studies. A prospectively collected and unbiased minor rear crash databank in the model of CIREN or NASS is highly desirable to verify or refute these results for the U.S. population since the current study cohort may have been influenced by litigation.

2011-01-01

The law of August 22nd, 2002 concerning patients' rights (LPR) gave a new dimension to the relationship between the physician and the patient. According to this law, it is up to the physician to judge if a patient is able to exercise his own rights or if the patient needs assistance from a representative. In the particular case of the patient being a minor, this often leads to a difficult situation because of the absence of validated criteria to evaluate the capacity of judgment of a minor patient. The triangular relationship physician-patient-parents might be hampered when the parents are involved in a divorce. In daily practice, there are many questions concerning the physicians' attitude towards the rights of the minor patient, particularly in cases of medical intervention. By means of case histories, we describe several problematic situations: the right of free choice of the physician, the right of the minor to obtain informational privacy, obtaining consent for a medical intervention. In cases where there is a divorce, the situation is even more difficult. Solutions are provided to act as effectively as possible in the minors' interests and to offer support to the physician. Note: According to article 388 of the Belgian Civil Code a minor is a person, either male or female, who has not attained the age of 18 years.

Accessing medication information by ethnic minorities: barriers and possible solutions.

Science.gov (United States)

Schaafsma, Evelyn S; Raynor, Theo D; de Jong-van den Berg, Lolkje T

2003-10-01

This review discusses two main questions: how suitable is current consumer medication information for minority ethnic groups, and what are effective strategies to overcome existing barriers. The focus is on minority groups whose first language is not the language of the healthcare system. We searched electronic databases and printed scientific journals focusing on (ethnic) minorities, health and/or (intercultural) communication. We also asked a discussion group for references. We found only a few articles on intercultural communication on medication or pharmacy information and one article on the improvement of intercultural communication in the pharmacy. Barriers to the access of medication information by ethnic minorities include second language issues and cultural differences due to different health beliefs, together with the low socio-economic status often seen among ethnic minorities. Cultural differences also exist among different socio-economic classes rather than only among ethnic groups. Most often, informal interpreters are used to improve intercultural communication. However, this may result in miscommunication due to a lack of medical knowledge or training on the part of the interpreter. To minimise miscommunication, bilingual health professionals or health interpreters/advocates can be used, although communication problems may still occur. The effectiveness of written information depends on the literacy skills of the target population. Cultural, medical and dialect biases should be avoided by testing the material. Multimedia systems may be alternatives to conventional written information. Barriers that ethnic minorities face in accessing medication information and possible solutions involving counselling and additional tools were identified for pharmacy practice. However, more research is needed to develop effective strategies for patient counselling in pharmacy to meet the needs of ethnic minorities.

The Minor Actinide Laboratory (MA-lab) of the Institute for Transuranium Elements is a unique facility for the fabrication of fuels and targets containing minor actinides (MA). It is of key importance for research on Partitioning and Transmutation in Europe, as it is one of the only dedicated facilities for the fabrication of MA containing materials, either for property measurements or for the production of test pins for irradiation experiments. In this paper a detailed description of the MA-Lab facility and the fabrication processes developed to fabricate fuels and samples containing high content of minor actinides is given. In addition, experience gained and improvements are also outlined. (authors)

A minority perspective in the diagnosis of child language disorders.

Science.gov (United States)

Seymour, H N; Bland, L

1991-01-01

The effective diagnosis and treatment of persons from diverse minority language backgrounds has become an important issue in the field of speech and language pathology. Yet, many SLPs have had little or no formal training in minority language, there is a paucity of normative data on language acquisition in minority groups, and there are few standardized speech and language tests appropriate for these groups. We described a diagnostic process that addresses these problems. The diagnostic protocol we have proposed for a child from a Black English-speaking background characterizes many of the major issues in treating minority children. In summary, we proposed four assessment strategies: gathering referral source data; making direct observations; using standardized tests of non-speech and language behavior (cognition, perception, motor, etc.); and eliciting language samples and probes.

An optimization methodology for heterogeneous minor actinides transmutation

Science.gov (United States)

Kooyman, Timothée; Buiron, Laurent; Rimpault, Gérald

2018-04-01

In the case of a closed fuel cycle, minor actinides transmutation can lead to a strong reduction in spent fuel radiotoxicity and decay heat. In the heterogeneous approach, minor actinides are loaded in dedicated targets located at the core periphery so that long-lived minor actinides undergo fission and are turned in shorter-lived fission products. However, such targets require a specific design process due to high helium production in the fuel, high flux gradient at the core periphery and low power production. Additionally, the targets are generally manufactured with a high content in minor actinides in order to compensate for the low flux level at the core periphery. This leads to negative impacts on the fuel cycle in terms of neutron source and decay heat of the irradiated targets, which penalize their handling and reprocessing. In this paper, a simplified methodology for the design of targets is coupled with a method for the optimization of transmutation which takes into account both transmutation performances and fuel cycle impacts. The uncertainties and performances of this methodology are evaluated and shown to be sufficient to carry out scoping studies. An illustration is then made by considering the use of moderating material in the targets, which has a positive impact on the minor actinides consumption but a negative impact both on fuel cycle constraints (higher decay heat and neutron) and on assembly design (higher helium production and lower fuel volume fraction). It is shown that the use of moderating material is an optimal solution of the transmutation problem with regards to consumption and fuel cycle impacts, even when taking geometrical design considerations into account.

Sensitivity analysis of minor actinides transmutation to physical and technological parameters

International Nuclear Information System (INIS)

Kooyman, T.; Buiron, L.

2015-01-01

Minor actinides transmutation is one of the 3 main axis defined by the 2006 French law for management of nuclear waste, along with long-term storage and use of a deep geological repository. Transmutation options for critical systems can be divided in two different approaches: (a) homogeneous transmutation, in which minor actinides are mixed with the fuel. This exhibits the drawback of 'polluting' the entire fuel cycle with minor actinides and also has an important impact on core reactivity coefficients such as Doppler Effect or sodium void worth for fast reactors when the minor actinides fraction increases above 3 to 5% depending on the core; (b) heterogeneous transmutation, in which minor actinides are inserted into transmutation targets which can be located in the center or in the periphery of the core. This presents the advantage of decoupling the management of the minor actinides from the conventional fuel and not impacting the core reactivity coefficients. In both cases, the design and analyses of potential transmutation systems have been carried out in the frame of Gen IV fast reactor using a 'perturbation' approach in which nominal power reactor parameters are modified to accommodate the loading of minor actinides. However, when designing such a transmutation strategy, parameters from all steps of the fuel cycle must be taken into account, such as spent fuel heat load, gamma or neutron sources or fabrication feasibility. Considering a multi-recycling strategy of minor actinides, an analysis of relevant estimators necessary to fully analyze a transmutation strategy has been performed in this work and a sensitivity analysis of these estimators to a broad choice of reactors and fuel cycle parameters has been carried out. No threshold or percolation effects were observed. Saturation of transmutation rate with regards to several parameters has been observed, namely the minor actinides volume fraction and the irradiation time. Estimators of interest that have been

Global warming and allergy in Asia Minor.

Science.gov (United States)

Bajin, Munir Demir; Cingi, Cemal; Oghan, Fatih; Gurbuz, Melek Kezban

2013-01-01

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

Sexual Violence on Campus: Differences Across Gender and Sexual Minority Status.

Martin-Storey, Alexa; Paquette, Geneviève; Bergeron, Manon; Dion, Jacinthe; Daigneault, Isabelle; Hébert, Martine; Ricci, Sandrine

2018-06-01

Sexual violence is a pervasive problem on university campuses. Although previous work has documented greater vulnerability for sexual violence among sexual and gender minority students, little is known about contextual variation in vulnerability to this kind of violence. The goals of the current study were (1) to identify vulnerability among sexual and gender minority students with regard to sexual violence, and (2) to explore if the context of this violence differs across sexual and gender minority status. Undergraduate students (ages 18-24) from six francophone universities in Quebec, Canada (N = 4,264) completed online questionnaires regarding their experience of sexual violence, as well as the context of these acts (e.g., the gender of the perpetrator, the status of the perpetrator, and the location of the violence). They also provided information regarding their sexual and gender minority status. Binary logistic regressions were conducted to assess for variation in experiencing sexual violence across sexual and gender minority status. Transgender/nonbinary students generally reported higher levels of sexual violence than their cisgender peers, while variation occurred with regard to vulnerability across sexual identity subgroups. Few differences in context were observed across sexual minority identity. Transgender/nonbinary students were significantly more likely to report sexual violence in athletic contexts and during volunteering activities compared to their cisgender peers. Findings highlight the higher levels of vulnerability for sexual violence among gender minority and some sexual minority university students. They also point to the contexts in which such violence occurs, suggesting specific strategies for prevention. Copyright © 2018 The Society for Adolescent Health and Medicine.

2017-06-01

Little population-based work has been published about the mental health of adolescents with both sexual/gender (SG) and ethnic minority (i.e. double minority) status. This study aimed to provide an overview on their mental health. Analysis of data from a total of 17,607 high school students from New Zealand's 2007 and 2012 cross-sectional nationally representative Adolescent Health Surveys, including a total of 1306 (7.4%) SG minority participants, of whom 581 (3.3%) were also an ethnic minority. SG minority status, minority ethnicity, and female sex were associated with higher mental distress and poorer well-being. Generally speaking, double minority students reported poorer mental health than SG majority students of the same ethnicity, but reported better mental health than SG minority New Zealand European students. Explanations and future directions for research were suggested to further explore how double minority students negotiate mental health in the context of their communities/cultures in New Zealand.

Chinese attitudes towards sexual minorities in Hong Kong: Implications for mental health.

Science.gov (United States)

Kwok, Diana K; Wu, Joseph

2015-01-01

Intolerant attitudes and sexual prejudice against sexual minorities (lesbian, gay, bisexual, and questioning/queer-LGBQ) has been a long-standing global concern. In this article, Chinese attitudes towards sexual minorities are examined with reference to the cultural context in Hong Kong, a place where the East has intermingled with the West for over a century. Chinese sexuality manifested in Hong Kong is a mix of Confucian ideology and Christian thought. Traditional Confucian values of xiao (filial piety) and conventional religious thoughts of Christianity together influence Chinese attitudes towards sexual minorities. Though many governmental policies have been put in place and numerous laws have been enacted to protect the human rights of underprivileged and disadvantaged groups over the past few decades, sexual minorities are frequently being excluded from most of these protections. In Hong Kong, sexual prejudice exists not only among the general public, but also among educators and mental health professionals. Thus, Chinese sexual minorities experience sexual prejudice and minority stress in Hong Kong under unique cultural circumstances. This calls for inclusive policies and an embracing attitude towards sexual minorities so their mental health will not suffer.

Phoenix type concepts for transmutation of LWR waste minor actinides

International Nuclear Information System (INIS)

Segev, M.

1994-01-01

A number of variations on the original Phoenix theme were studied. The basic rationale of the Phoenix incinerator is making oxide fuel of the LWR waste minor actinides, loading it in an FFTF-like subcritical core, then bombarding the core with the high current beam accelerated protons to generate considerable energy through spallation and fission reactions. As originally assessed, if the machine is fed with 1600 MeV protons in a 102 mA current, then 8 core modules are driven to transmute the yearly minor actinides waste of 75 1000 MW LWRs into Pu 238 and fission products; in a 2 years cycle the energy extracted is 100000 MW d/T. This performance cannot be substantiated in a rigorous analysis. A calculational consistent methodology, based on a combined execution of the Hermes, NCNP, and Korigen codes, shows, nonetheless that changes in the original Phoenix parameters can upgrade its performance.The original Phoenix contains 26 tons minor actinides in 8 core modules; 1.15 m 3 module is shaped for 40% neutron leakage; with a beam of 102 mA the 8 modules are driven to 100000 MW/T in 10.5 years, burning out the yearly minor actinide waste of 15 LWRs; the operation must be assisted by grid electricity. If the 1.15 m 3 module is shaped to allow only 28% leakage, then a beam of 102 mA will drive the 8 modules to 100000 MW/T in 3.5 years, burning out the yearly minor actinides waste of 45 LWRs. Some net grid electricity will be generated. If 25 tons minor actinides are loaded into 5 modules, each 1.72 m 3 in volume and of 24% leakage, then a 97 mA beam will drive the module to 100000 MW/T in 2.5 years, burning out the yearly minor actinides waste of 70 LWRs. A considerable amount of net grid electricity will be generated. If the lattice is made of metal fuel, and 26 tons minor actinides are loaded into 32 small modules, 0.17 m 3 each, then a 102 mA beam will drive the modules to 100000 MW/T in 2 years, burning out the yearly minor actinides waste of 72 LWRs.

Retaining minorities in engineering: Assessment of a program prototype

Science.gov (United States)

Good, Jennifer Marie (Phillips)

Program assessment is an essential part of healthy program development. Assessment should include multiple considerations, dimensions, and outcomes that match the program's objectives. As a newly formed retention program, the Auburn University Minority Engineering Program, designed to help pre-engineering minority students make the transition into their freshman year of university studies, incorporated evaluation and assessment into all three components of the program (the interactive learning laboratory, critical-thinking workshops, and Sunday-evening tutorials) from the program's inception. If students successfully adapted to the university environment and the demands of the pre-engineering course of study, then retention of minority students in the College of Engineering should improve. Data were gathered on the students involved in the various program components. Students who entered the Minority Engineering Program were pre- and posttested on three standardized subtests (critical thinking, mathematics, and science reasoning) of the Collegiate Assessment of Academic Proficiency. The first-quarter grade-point averages of the students were also gathered to compare their grades to freshman students in previous quarters within the College of Engineering. Qualitative data were also gathered on this same group of students. An analysis of the data revealed that student achievement is affected by involvement in the Minority Engineering Program. Specifically, the first quarter grade point averages of students involved in the program exceeded those of their peers in earlier years of study prior to the program's existence. In addition, mathematics and science reasoning scores on standardized tests increased pre- to postintervention. Comments collected in journals and files also demonstrated use of critical-thinking and problem-solving skills employed by the students. Recommendations for alterations of the program were made based on the outcome of the program evaluation

Riley, Margaret; Ahmed, Sana; Reed, Barbara D; Quint, Elisabeth H

2015-08-01

Minor adolescent patients have a legal right to access certain medical services confidentially without parental consent or notification. We sought to assess physicians' knowledge of these laws, attitudes around the provision of confidential care to minors, and barriers to providing confidential care. An anonymous online survey was sent to physicians in the Departments of Family Medicine, Internal Medicine-Pediatrics, Obstetrics/Gynecology, and Pediatrics at the University of Michigan. Response rate was 40% (259/650). The majority of physicians felt comfortable addressing sexual health, mental health, and substance use with adolescent patients. On average, physicians answered just over half of the legal knowledge questions correctly (mean 56.6% ± 16.7%). The majority of physicians approved of laws allowing minors to consent for confidential care (90.8% ± 1.7% approval), while substantially fewer (45.1% ± 4.5%) approved of laws allowing parental notification of this care at the physician's discretion. Most physicians agreed that assured access to confidential care should be a right for adolescents. After taking the survey most physicians (76.6%) felt they needed additional training on confidentiality laws. The provision of confidential care to minors was perceived to be most inhibited by insurance issues, parental concerns/relationships with the family, and issues with the electronic medical record. Physicians are comfortable discussing sensitive issues with adolescents and generally approve of minor consent laws, but lack knowledge about what services a minor can access confidentially. Further research is needed to assess best methods to educate physicians about minors' legal rights to confidential healthcare services.

Cora-Bramble, Denice; Zhang, Kehua; Castillo-Page, Laura

2010-09-01

To explore whether there is a relationship between resilience and academic productivity of minority faculty members in U.S. academic health centers. For the purposes of the study, the authors defined academic productivity as peer-reviewed and non-peer-reviewed publications, grants, and academic promotion. In 2007, the authors simultaneously collected quantitative and qualitative data by using a triangulation (mixed-method) design. Past participants in the Association of American Medical Colleges' Minority Faculty Career Development Seminar completed the Web-based 70-item Personal Resilience Questionnaire (PRQ). In addition, two focus groups were conducted with past seminar participants. Seventy-four minority faculty members completed the PRQ, and 15 participated in the two focus groups. The quantitative data showed a positive correlation between demographic, educational, and academic productivity variables and certain resilience subscale scores. Common themes that emerged from the qualitative data were categorized under four major domains: existing barriers to academic advancement, internal protective factors or cultural buffers, external institutional or environmental facilitators, and necessary attributes for ensuring academic productivity and advancement. Certain resilience subscales showed correlation with academic productivity of minority faculty members, and specific personal and/or cultural characteristics were identified as enablers. Minority faculty members may benefit from skill development and coaching that extends beyond the traditional scope of faculty development programs and that specifically targets modifiable resilience characteristics. Additional research is needed, but such nontraditional, resilience-centered intervention strategies may positively affect the advancement of minority faculty in academic medicine.

Weber, Amanda; Collins, Shelly-Ann; Robinson-Wood, Tracy; Zeko-Underwood, Elda; Poindexter, Bianca

2018-01-01

In recent years, understanding prejudice and discrimination toward minorities has developed to include the investigation of microaggressions. Microaggressions are brief and commonplace verbal, behavioral, or environmental indignities. They are intentional or unintentional and communicate hostile, derogatory, or negative slights toward racial and sexual minorities. The purpose of this phenomenological study is to chronicle the prevalence and type of microaggressions experienced among a sample of 18 highly educated and racially diverse sexual minorities, 24-65 years of age. The impact of microaggressions on physical and psychological health is central to our investigation. Thematic data analysis was used to analyze 14 interviews and one focus group, which resulted in the following themes of microaggressions: (a) discomfort/disapproval with LGBT experience, (b) assumption of universal experience, (c) traditional gender role stereotyping, (d) denial of personal privacy, (e) exoticization, (f) ascription of intelligence, (g) policing bodies, and (h) assumption of criminality. Research findings may have implications for the development of interventions that can serve clinicians in their therapeutic work with microaggressed sexual minorities across racial diversity.

Full Text Available  Background & objective: β-Thalassemia minor is an asymptomatic hereditary disease. The first study on the relation of renal tubular dysfunction and β-thalassemia minor was performed in 2002 but those studies seem inadequate.The main goal of this study is through evaluation of renal tubular function in 100 patients with thalassemia minor. Materials & Methods: 100 patients with β- thalassemia which confirmed by hemoglobin electrophoresis and CBC as well as RBC indices were studied.14 out of 100 cases exit because of Urinary Tract Infection, diabetes mellitus or hypertension.Complete chemistry profile was performed on serum and urine of all reminder 86 patients (46 female and 40 male. Patients classified into two groups: β-thalassemia minor with anemia and without anemia. Another control group include 50 healthy individuals also considered.Then data analyzed by proper statistical methods. Results: 20 out of 86 reminder cases e.g. 24% showed at least one index of renal tubular dysfunction.58% of patients was been anemic and 42% non anemic. The most prominent tubular dysfunction was seen in a 29 years old lady with glucosuria and without anemia. conclusion: β-Thalassemia minor is common in Iran specially in Fars province. This study revealed significant renal tubular dysfunction in patient with β-thalassemia minor. So it is necessary to check out thalassemic patients for renal function tests periodically. Key words: β-thalassemia, minor,renal tubular dysfunction

Criterion and Divergent Validity of the Sexual Minority Adolescent Stress Inventory

2017-11-01

Full Text Available Sexual minority adolescents (SMA consistently report health disparities compared to their heterosexual counterparts, yet the underlying mechanisms of these negative health outcomes remain unclear. The predominant explanatory model is the minority stress theory; however, this model was developed largely with adults, and no valid and comprehensive measure of minority stress has been developed for adolescents. The present study validated a newly developed instrument to measure minority stress among racially and ethnically diverse SMA. A sample of 346 SMA aged 14–17 was recruited and surveyed between February 2015 and July 2016. The focal measure of interest was the 64-item, 11-factor Sexual Minority Adolescent Stress Inventory (SMASI developed in the initial phase of this study. Criterion validation measures included measures of depressive symptoms, suicidality and self-harm, youth problem behaviors, and substance use; the general Adolescent Stress Questionnaire (ASQ was included as a measure of divergent validity. Analyses included Pearson and tetrachoric correlations to establish criterion and divergent validity and structural equation modeling to assess the explanatory utility of the SMASI relative to the ASQ. SMASI scores were significantly associated with all outcomes but only moderately associated with the ASQ (r = −0.13 to 0.51. Analyses revealed significant associations of a latent minority stress variable with both proximal and distal health outcomes beyond the variation explained by general stress. Results show that the SMASI is the first instrument to validly measure minority stress among SMA.

2017-12-01

Social stress resulting from stigma, prejudice, and discrimination-"minority stress"-negatively impacts sexual minority individuals' health and relational well-being. The present study examined how being in a same-sex couple can result in exposure to unique minority stressors not accounted for at the individual level. Relationship timeline interviews were conducted with 120 same-sex couples equally distributed across two study sites (Atlanta and San Francisco), gender (male and female), and relationship duration (at least six months but less than three years, at least three years but less than seven years, and seven or more years). Directed content analyses identified 17 unique couple-level minority stressors experienced within nine distinct social contexts. Analyses also revealed experiences of dyadic minority stress processes (stress discrepancies and stress contagion). These findings can be useful in future efforts to better understand and address the cumulative impact of minority stress on relational well-being and individual health.

Minority Stress and Stress Proliferation Among Same-Sex and Other Marginalized Couples.

Science.gov (United States)

LeBlanc, Allen J; Frost, David M; Wight, Richard G

2015-02-01

Drawing from 2 largely isolated approaches to the study of social stress-stress proliferation and minority stress-the authors theorize about stress and mental health among same-sex couples. With this integrated stress framework, they hypothesized that couple-level minority stressors may be experienced by individual partners and jointly by couples as a result of the stigmatized status of their same-sex relationship-a novel concept. They also consider dyadic minority stress processes, which result from the relational experience of individual-level minority stressors between partners. Because this framework includes stressors emanating from both status- (e.g., sexual minority) and role-based (e.g., partner) stress domains, it facilitates the study of stress proliferation linking minority stress (e.g., discrimination), more commonly experienced relational stress (e.g., conflict), and mental health. This framework can be applied to the study of stress and health among other marginalized couples, such as interracial/ethnic, interfaith, and age-discrepant couples.

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

2016-11-01

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

2017-06-01

The management of patients with acute transient ischemic attack (TIA) or minor stroke is highly variable. Whether hospitalization of such patients significantly improves short-term clinical outcome is unknown. We assessed the short-term clinical outcome associated with inpatient versus outpatient management of patients with TIA or minor stroke. We evaluated a consecutive series of patients with acute TIA or minor ischemic stroke (NIH Stroke Scale score ≤ 3) presenting to a single emergency department (ED). We randomized patients to either hospital-based or outpatient-based management. All patients underwent interview and examination 7-10 days following the index event. This study included 100 patients, 41 with TIA and 59 with minor stroke. Nineteen (46%) of the TIA patients and 29 (49%) of the minor stroke patients randomized to hospital management, and the remaining 22 TIA patients and 30 minor stroke patients randomized to outpatient-based management. In the patients with a minor stroke, neurologic worsening occurred in 6 out of 29 (21%) in the inpatient arm compared with 3 out of 30 (10%) in the outpatient arm ( p = 0.3). In none of these cases was acute interventional therapy or need for urgent admission considered medically appropriate. In the patients with a TIA, recurrence of a TIA occurred in 2 out of 19 (11%) in the inpatient arm compared with 2 out of 22 (9%) in the outpatient arm ( p = 1). None of the patients with a TIA randomized to the inpatient arm experienced a stroke compared with 1 out of 22 in the outpatient arm ( p = 1). There were no deaths in either group. Routine hospitalization of all patients with TIA or minor ischemic stroke may not positively affect short-term clinical outcome.

Cross-border mergers and minority protection
An open-ended harmonization

Directory of Open Access Journals (Sweden)

Marieke Wyckaert

2008-03-01

Full Text Available Minority protection is an important, though difficult, issue in company law, and a subtle balance must be struck between the legitimate interests of the majority and minority shareholder(s. The rules on minority protection in the context of the Cross-border Mergers Directive, which was recently adopted and should have been transposed into Member States’ national law towards the end of 2007, are examined in this paper. The authors analyse how minority shareholders are protected within the scope of this Directive and how some of the Member States (such as Germany, Italy, Belgium and the Netherlands have transposed or will transpose some of these protective provisions. The different levels of minority protection (information rights, consultation rights, rights to challenge majority decisions and other specific rights are considered, as well as which types of shareholders can benefit from such protection, and why they should be afforded protection. With respect to the last question, the authors conclude that the change in corporate law encountered especially by the shareholders of the disappearing company seems to be the major rationale underlying the European legislator's decision to introduce minority protection (but not oblige Member States to do so. The authors submit that this reflects too narrow a vision on the need for minority protection because it ignores the fact that the change of the corporate form as a consequence of a merger is in itself sufficient rationale for protecting minority shareholders. It remains somewhat of a mystery as to why the European legislator, while confirming that a cross-border merger should be subject to the same rules as a national merger, has created one possible and very vague exception to that rule.

Thalassemia and hemoglobinopathies in an ethnic minority group in Central Vietnam: implications to health burden and relationship between two ethnic minority groups.

Thalassemia is a genetic condition that can result in long and expensive treatments, and severe thalassemia may lead to death if left untreated. Couples contributing two genes for thalassemia place their children at particular risk for severe thalassemia. Gene frequency of thalassemia varies in Vietnam, but presents remarkably high levels among some ethnic minority groups. Limited information about thalassemia frequency makes prevention and control of thalassemia difficult. This study aimed to determine gene frequency of certain types of thalassemia among 390 women of reproductive age of the Ta-Oi ethnic minority. Hemoglobin and DNA analyses were carried out to diagnose thalassemia and hemoglobinopathies. Of the total participants, 56.1% (95% CI = 51.1-61.1) carried thalassemia genes. A remarkably high frequency of hemoglobin Constant Spring (Hb CS) of 23.8% (95% CI = 19.7-28.4) was noted. The frequency of α + -thalassemia (-3.7 kb deletion) was 26.4% (95% CI = 22.1-31.1), while hemoglobin E (Hb E) and hemoglobin Paksé (Hb Ps) were identified at frequencies of 14.6 (95% CI = 11.2-18.5) and 2.6% (95% CI = 1.4-5.0), respectively. Further analysis of α-globin gene haplotype revealed the same Hb CS haplotype (+ - M + + -) as of the Co-Tu minority, a neighboring minority of the Ta-Oi, indicating that these two minorities may share the same ancestors. This information will be helpful for further studies in population genetics, as well as the development prevention and control program in the region.

Factors affecting minority population proximity to hazardous facilities

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.

Anatomical study of minor alterations in neonate vocal folds.

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.

Solar-wind minor ions: recent observations

International Nuclear Information System (INIS)

Bame, S.J.

1982-01-01

During the years following the Solar Wind Four Conference at Burghausen our knowledge of the solar wind ion composition and dynamics has grown. There have been some surprises, and our understanding of the evolution of the solar wind has been improved. Systematic studies have shown that the minor ions generally travel with a common bulk speed and have temperatures roughly proportional to their masses. It has been determined that the 3 He ++ content varies greatly; 3 He ++ / 4 He ++ ranges from as high as 10 2 values to below 2 x 10 - 4 . In some solar wind flows which can be related to energetic coronal events, the minor ions are found in unusual ionization states containing Fe 16 + as a prominent ion, showing that the states were formed at unusually high temperatures. Unexpectedly, in a few flows substantial quantities of 4 He + have been detected, sometimes with ions identifiable as O 2 + and O 3 + . Surprisingly, in some of these examples the ionization state is mixed showing that part of the plasma escaped the corona without attaining the usual million-degree temperatures while other parts were heated more nearly in the normal manner. Additionally, detailed studies of the minor ions have increased our understanding of the coronal expansion. For example, such studies have contributed to identifying near equatorial coronal streamers as the source of solar wind flows between high speed streams

Ethical Considerations for the Participation of Children of Minor Parents in Clinical Trials.

Children of minor parents are under-represented in clinical trials. This is largely because of the ethical, legal, and regulatory complexities in the enrolment, consent, and appropriate access of children of minor parents to clinical research. Using a case-based approach, we examine appropriate access of children of minor parents in an international vaccine trial. We first consider the scientific justification for inclusion of children of minor parents in a vaccine trial. Laws and regulations governing consent generally do not address the issue of minor parents. In their absence, local community and cultural contexts may influence consent processes. Rights of the minor parent include dignity in their role as a parent and respect for their decision-making capacity in that role. Rights of the child include the right to have decisions made in their best interest and the right to the highest attainable standard of health. Children of minor parents may have vulnerabilities related to the age of their parent, such as increased rates of poverty, that have implications for consent. Neuroscience research suggests that, by age 12-14 years, minors have adult-level capacity to make research decisions in situations with low emotion and low distraction. We conclude with a set of recommendations based on these findings to facilitate appropriate access and equity related to the participation of children of minor parents in clinical research.

Campus Climate and the Underrepresented Minority Engineering Student Experience: A Critical Race Study

Science.gov (United States)

Mayes, Terrance

In the current technological era, the number of minorities in science, technology, engineering, and mathematics (STEM) is a crucial factor in predetermining the economic growth of the United States. Since the minority population is growing at much faster rates than the non-minority population, the lack of proportionate production of minority engineers poses a threat to the United States' ability to remain a global competitor in technological innovation. Sixty-three per cent (63%) of undergraduate students who enter engineering majors continue on to graduate in that major. The graduation rate, however, for African-American, Hispanic, and Native-American students in engineering is significantly lower at 39%. As this group represents only a small fraction of the annual student enrollment, engineering programs are graduating these minority groups at rates that are greatly disproportionate to United States demographics. Therefore, researchers are thoroughly investigating certain initiatives that promote academic success among underrepresented minority students in engineering. Colleges and universities have attempted to address the growing achievement gap between underrepresented minority and non-minority engineering students, predominately through various deficit-based interventions, focusing on the student's flaws and problems. As the pipeline for minorities in engineering continues to narrow, it begs the question of whether institutions are focusing on the right solutions to the problem. Critical Race Theory scholars argue that colleges and universities must address institutional climate issues around students, such as racism, microaggressions, and marginalization, before members of oppressed groups can truly succeed. This dissertation explored the unique experiences of underrepresented minority engineering students in a predominately White and Asian campus.

The use of silver nanoparticles (AgNPs) in commercial products has increased significantly in recent years. Although there has been some attempt to determine the toxic effects of AgNPs, there is little information on aquatic plants which have a vital role in ecosystems. This study reports the use of Lemna minor L. clone St to investigate the phytotoxicity of AgNPs under modified OECD test conditions. AgNPs were synthesised, characterised and subsequently presented to the L. minor. Results showed that inhibition of plant growth was evident after exposure to small ({approx}20 nm) and larger ({approx}100 nm) AgNPs at low concentrations (5 {mu}g L{sup -1}) and this effect became more acute with a longer exposure time. There was a linear dose-response relationship after 14 d exposure. Using predicted environmental concentrations for wastewaters it was found that AgNPs may pose a significant potential risk to the environment. - Highlights: > Silver nanoparticles are toxic to Lemna minor at concentrations of 5 {mu}g L{sup -1}. > The effect of silver nanoparticles varies with size and concentration. > Standard toxicity tests are not appropriate for application to NPs. > Silver nanoparticles pose a potential environmental risk based on modelled environmental concentrations. - Silver nanoparticles are toxic to Lemna minor at low concentrations and constitute a significant environmental risk.

Hammig, Bart; Daniel-Dobbs, Page; Blunt-Vinti, Heather

2017-05-01

Electronic cigarettes (e-cigarette) use among youth is a pressing public health issue, with prevalence of use surpassing that of tobacco cigarettes. While research concerning e-cigarettes has proliferated in recent years, there is a dearth of information regarding those whose first exposure to tobacco products was an e-cigarette. To examine factors associated with e-cigarette initiation among minority youth in the United States. Data on minority students in middle and high schools in the United States derived from the 2014 National Youth Tobacco Survey (NYTS) were sampled (weighted N = 27,294,454). We examined e-cigarette initiation among minority youth using logistic regression models to identify related factors. In 2014, 736,158 minority youth were e-cigarette initiators. Odds of e-cigarette initiation was highest among Hispanic youth [adjusted odds ratio (AOR) = 2.70; 95% confidence interval (CI) = 1.60-4.56]. Exposure to e-cigarette advertising (AOR = 1.64; 95% CI = 1.07-2.50), perceptions of little to no harm (AOR = 7.08; 95% CI = 4.03-12.46), and believing e-cigarettes were less addictive than tobacco (AOR = 2.15; 95% CI = 1.52-3.02) were associated with e-cigarette initiation. Odds of initiating e-cigarette use was highest among Hispanic youth. Among minority youth, e-cigarette initiation was associated with perceptions of harm and addiction potential, as well as exposure to e-cigarette advertising. Therefore, prevention efforts targeting minority youth who are at risk of becoming e-cigarette initiators may benefit by incorporating these factors into prevention campaigns.

Can galaxy growth be sustained through HI-rich minor mergers?

Science.gov (United States)

Lehnert, M. D.; van Driel, W.; Minchin, R.

2016-05-01

Local galaxies with specific star-formation rates (star-formation rate per unit mass; sSFR ~ 0.2-10 Gyr-1) that are as high as distant galaxies (z ≈ 1-3), are very rich in Hi. Those with low stellar masses, M⋆ = 108-9 M⊙, for example, have MHI/M⋆ ≈ 5-30. Using continuity arguments, whereby the specific merger rate is hypothesized to be proportional to the specific star-formation rate, along with Hi gas mass measurements for local galaxies with high sSFR, we estimate that moderate-mass galaxies, M⋆ = 109-10.5 M⊙, can acquire enough gas through minor mergers (stellar mass ratios ~4-100) to sustain their star formation rates at z ~ 2. The relative fraction of the gas accreted through minor mergers declines with increasing stellar mass, and for the most massive galaxies considered, M⋆ = 1010.5-11 M⊙, this accretion rate is insufficient to sustain their star formation. We checked our minor merger hypothesis at z = 0 using the same methodology, but now with relations for local normal galaxies, and find that minor mergers cannot account for their specific growth rates, in agreement with observations of Hi-rich satellites around nearby spirals. We discuss a number of attractive features, such as a natural downsizing effect, in using minor mergers with extended Hi disks to support star formation at high redshift. The answer to the question posed by the title, "Can galaxy growth be sustained through Hi-rich minor mergers?", is "maybe", but only for relatively low-mass galaxies and at high redshift.

2018-01-01

Full Text Available This paper aims at discussing the role of the minor characters in William Shakespeare's Twelfth Night and A Midsummer Night's Dream. The study assumes that without the first group of minor characters, associated with Olivia, the play Twelfth Night would lose much of its humor, and without the second group, associated with Sebastian, the play would fall apart. On the other hand, in Shakespeare's A Midsummer Night's Dream minor characters play important roles, without them, the action dose not ran smoothly, or does not ran at all. The paper falls into three sections. Section one deals with the role of each minor character in Twelfth Night.  Section two focuses on the minor characters in A Midsummer Night's Dream. Section three is a conclusion which sums up the findings of the study.

Laws prohibiting the sale of tobacco to minors: impact and adverse consequences.

Science.gov (United States)

Etter, Jean-François

2006-07-01

This paper discusses the consequences of laws that prohibit the sale of tobacco to minors. When enforced, such laws may decrease tobacco sales to minors, but local authorities are often reluctant to enforce these laws. However, the prohibition of tobacco sales to minors is often followed by an increase in the use of tobacco obtained from social sources, mainly family and friends. Importantly, these laws do not decrease smoking prevalence among minors. Several local laws prohibit youths from purchasing, using, and possessing tobacco. However, these laws shift responsibility from retailers to youth, criminalizing young smokers. Those who advocate this type of approach have not documented the adverse consequences of laws that prohibit minors from purchasing, using, or possessing tobacco. In conclusion, youth access laws are ineffective and are not based on sound science.

Minors' rights to consent to treatment: navigating the complexity of State laws.

Science.gov (United States)

Vukadinovich, David M

2004-01-01

State laws recognize that a competent adult patient has the right to consent to or refuse medical treatment. While the law is clear with regard to the right of competent adults, state statutes are more complicated when the patient is a minor. While the law should, and does, attempt to balance the rights and obligations of parents and guardians against the access and privacy rights of minors, complicated state statutory schemes often fail to simultaneously address those contrasting goals in a consistent and uniform manner. The result is a confusing set of seemingly arbitrary and sometimes conflicting provisions that require the detailed attention of healthcare providers to ensure legal compliance. With the aim of helping healthcare practitioners meet their legal obligations, this Article examines state laws governing minor's consent rights byfocusing on the instances in which a minor's parent, guardian, or other authorized adult is permitted to consent to treatment on behalf of a minor and the instances in which a minor is authorized to act independent of adult intervention.

Radial diffusion of a minority species in a tokamak due to ICRH

International Nuclear Information System (INIS)

Vacca, L.

1993-01-01

The author studies the transport of a minority species in a scenario where minority ions in a tokamak are heated by fast Alfven waves having a resonance layer in a tokamak. He does not assume the minority distribution function to be a Maxwellian at leading order, as transport theory generally assumes, but adopts a more realistic model where the strong anisotropy of the distribution function is accounted for. This anisotropy has been observed in experiments and is predicted by numerical calculations based on Fokker-Planck equation with quasilinear diffusion. By adopting a different ordering from that used in previous work on transport due to waves and taking moments of the kinetic equation which includes the rf driving term, he calculates the fluxes of the resonant minority species accounting for collisions of minority with bulk electrons and ion species. Finally he makes comparison of fluxes of rf-heated minority with standard neoclassical predictions (no rf source present) showing the enhancement in transport introduced by the presence of both a strongly anisotropic distribution function and an rf source

Bioremediation of an iron-rich mine effluent by Lemna minor.

Teixeira, S; Vieira, M N; Espinha Marques, J; Pereira, R

2014-01-01

Contamination of water resources by mine effluents is a serious environmental problem. In a old coal mine, in the north of Portugal (São Pedro da Cova, Gondoma),forty years after the activity has ended, a neutral mine drainage, rich in iron (FE) it stills being produced and it is continuously released in local streams (Ribeiro de Murta e Rio Ferreira) and in surrounding lands. The species Lemna minor has been shown to be a good model for ecotoxicological studies and it also has the capacity to bioaccumulate metals. The work aimed test the potential of the species L. minor to remediate this mine effluent, through the bioaccumulation of Fe, under greenhouse experiments and, at the same time, evaluate the time required to the maximum removal of Fe. The results have shown that L. minor was able to grow and develop in the Fe-rich effluent and bioaccumulating this element. Throughout the 21 days of testing it was found that there was a meaningful increase in the biomass of L. minor both in the contaminated and in the non-contaminated waters. It was also found that bioaccumulation of Fe (iron) occurred mainly during the first 7 days of testing. It was found that L. minor has potential for the bioremediation of effluents rich in iron.

Ion heating in minority ICRH experiments on JET

Start, D.F.H.; Bhatnagar, V.; Bures, M.

1991-06-01

Bulk ion heating by high power H-minority ICRH has been demonstrated in JET during both pellet enhanced performance H-mode experiments (PEP + H - mode) and in density limit studies. In the PEP + H - mode plasmas the electron and ion temperatures both reached 10 keV at an electron density of 7 x 10 19 /m 3 . According to Fokker-Planck calculations the power from the minority was transfered almost equally to the electrons and majority ions as a result of both the high electron density, n e , and the high minority density, n h , (n h /n e ≅ 0.15). For the first time with ICRH on JET a central ion temperature greater than the central electron temperature was achieved. In the density limit experiments which involved strong gas puffing into limiter discharges, there was strong evidence of a transfer from electron heating to ion heating as the electron density was ramped up to 8 x 10 19 /m 3 .

2014-01-01

Arsenic is hazardous and causes several ill effects on human beings. Phytoremediation is the use of aquatic plants for the removal of toxic pollutants from external media. In the present research work, the removal efficiency as well as the arsenic uptake capacity of duckweed Lemna minor has been studied. Arsenic concentration in water samples and plant biomass were determined by AAS. The relative growth factor of Lemna minor was determined. The duckweed had potential to remove as well as uptake arsenic from the aqueous medium. Maximum removal of more than 70% arsenic was achieved atinitial concentration of 0.5 mg/1 arsenic on 15th day of experimental period of 22 days. Removal percentage was found to decrease with the increase in initial concentration. From BCF value, Lemna minor was found to be a hyperaccumulator of arsenic at initial concentration of 0.5 mg/L, such that accumulation decreased with increase in initial arsenic concentration.

MINORITY LANGUAGE POLICY REGARDING PERSONAL NAMES – AN OVERVIEW

Directory of Open Access Journals (Sweden)

Justyna Walkowiak

2011-01-01

Full Text Available Language Policy (LP with language planning as its implementation is now a well-established field; yet, as evidenced by the scarcity of scholarly literature, seldom concerned with personal names. The paper looks at personal names (given names and surnames and discusses the ways in which they can be perceived as objects of minority LP. Policies regarding personal names are analysed within the framework of the traditional division of language planning into status, corpus and acquisition planning. These policies are then further examined according to other dimensions: what the object of a LP is, who its agent is, what motivates a LP, what effects it exerts, and how a LP is carried out. Finally, the paper looks at EU minority legislation with reference to personal names,especially at the country-specific opinions which reflect the FCNM monitoring process, highlighting areas of controversy. In conclusion, it is shown how vital personal names are to personal and group identity and, consequently, how control over them helps the nation-state control a minority, although – it is argued – not every regulation constitutes a minority LP.

Comparison calculations for an accelerator-driven minor actinide burner

International Nuclear Information System (INIS)

2002-01-01

International interest in accelerator-driven systems (ADS) has recently been increasing in view of the important role that these systems may play as efficient minor actinide and long-lived fission-product (LLFP) burners and/or energy producers with an enhanced safety potential. However, the current methods of analysis and nuclear data for minor actinide and LLFP burners are not as well established as those for conventionally fuelled reactor systems. Hence, in 1999, the OECD/NEA Nuclear Science Committee organised a benchmark exercise for an accelerator-driven minor actinide burner to check the performances of reactor codes and nuclear data for ADS with unconventional fuel and coolant. The benchmark model was a lead-bismuth-cooled subcritical system driven by a beam of 1 GeV protons. This report provides an analysis of the results supplied by seven participants from eight countries. The analysis reveals significant differences in important neutronic parameters, indicating a need for further investigation of the nuclear data, especially minor actinide data, as well as the calculation methods. This report will be of particular interest to reactor physicists and nuclear data evaluators developing nuclear systems for nuclear waste management. (authors)

Ethnic Minorities: Elements in Defining and Hierarchisation of the Right to Difference

Directory of Open Access Journals (Sweden)

Jadranka Čačić-Kumpes

2005-09-01

Full Text Available The theme that this paper examines are minorities, or rather ethnic minorities, which are central within the framework of social phenomena and processes linked to the multiethnic and multicultural structure of contemporary societies. Proceeding from the assumption that clarity of concepts is a precondition for understanding and solving problems pertaining to ethnic minorities, the authors provide a critique of the definitions and differentiations of concepts from which, in concrete societies and in specific ways, the rights of ethnic minorities mainly derive. The problem is posed in the context of contemporary societies, especially the immigration societies of the European Union, and the authors note the ethnic heterogeneity of the latter and the declared general consensus on the right to difference and on the importance of this right. Comparing, on the one hand, the ethnic structures of fifteen countries of the European Union (based on census data and estimations, and on the other hand data pertaining to the legislative regulation of minority protection in these countries, the authors conclude that various forms of selective denial of equality of the right to difference are in action. Contemporary divisions distinguishing between formerly disprivileged traditional minorities that are striving towards their revitalisation, and new ethnic minorities that are being formed out of immigrant populations, open possibilities for new forms of discrimination. Therefore, the authors further conclude that an attempt should be made to make minority rights equal, also since establishing hierarchies of rights, as has been shown throughout history, may lead to frustrations with long-term consequences.

School absenteeism and mental health among sexual minority youth and heterosexual youth.

Burton, Chad M; Marshal, Michael P; Chisolm, Deena J

2014-02-01

Adolescent school absenteeism is associated with negative outcomes such as conduct disorders, substance abuse, and dropping out of school. Mental health factors, such as depression and anxiety, have been found to be associated with increased absenteeism from school. Sexual minority youth (youth who are attracted to the same sex or endorse a gay, lesbian, or bisexual identity) are a group at risk for increased absenteeism due to fear, avoidance, and higher rates of depression and anxiety than their heterosexual peers. The present study used longitudinal data to compare sexual minority youth and heterosexual youth on excused and unexcused absences from school and to evaluate differences in the relations between depression and anxiety symptoms and school absences among sexual minority youth and heterosexual youth. A total of 108 14- to 19-years-old adolescents (71% female and 26% sexual minority) completed self-report measures of excused and unexcused absences and depression and anxiety symptoms. Compared to heterosexual youth, sexual minority youth reported more excused and unexcused absences and more depression and anxiety symptoms. Sexual minority status significantly moderated the effects of depression and anxiety symptoms on unexcused absences such that depression and anxiety symptoms were stronger predictors of unexcused absences for sexual minority youth than for heterosexual youth. The results demonstrate that sexual minority status and mental health are important factors to consider when assessing school absenteeism and when developing interventions to prevent or reduce school absenteeism among adolescents.

Exploration of the lived experiences of undergraduate science, technology, engineering, and mathematics minority students

Science.gov (United States)

Snead-McDaniel, Kimberly

An expanding ethnicity gap exists in the number of students pursuing science, technology, engineering, and mathematics (STEM) careers in the United States. The National Action Council for Minorities in Engineering revealed that the number of minorities pursuing STEM degrees and careers has declined over the past few years. The specific origins of this trend are not quite evident; one variable to consider is that undergraduate minority students are failing in STEM disciplines at various levels of education from elementary to postsecondary. The failure of female and minority students to enter STEM disciplines in higher education have led various initiatives to establish programs to promote STEM disciplines among these groups. Additional funding for minority STEM programs have led to a increase in undergraduate minority students entering STEM disciplines, but the minority students' graduation rate in STEM disciplines is approximately 7% lower than the graduation of nonminority students in STEM disciplines. This phenomenological qualitative research study explores the lived experiences of underrepresented minority undergraduate college students participating in an undergraduate minority-mentoring program. The following nine themes emerged from the study: (a) competitiveness, (b) public perception, (c) dedication, (d) self-perception, (e) program activities, (f) time management, (g) exposure to career and graduate opportunities, (h) rigor in the curriculum, and (i) peer mentoring. The themes provided answers and outcomes to better support a stronger minority representation in STEM disciplines.

Selling of tobacco products to minors has been banned since 1996 by the tobacco control law in Turkey. However, it is also important for the public to support practices that prevent the access of tobacco products to minors. In addition, every individual has the responsibility of carrying out society based programs that restrict access to tobacco products especially to children and the youths. Social sensitivity is considered an important factor in the prevention of tobacco use. This study aims to learn about the opinions and attitudes of adults with regards to minors access to tobacco products. The study was a descriptive study conducted in nine city centers in Turkey. The total number of participants reached was 3241. The questionnaire was developed by the research team and consisted of 22 questions concerning knowledge and behaviors of adults on restriction of tobacco sales to minors and their observations with regards tobacco sales to minors. Data was collected through face to face interview. Pearson chi-square test was used for the bivariate analysis whereas logistic regression was investigate the relationship between "the participant's response against tobacco sales to minors" and the following explanatory variables; "age", "educational status", "income level", "working status", "minors access to cigarettes", "smoking ratio in high school" and "sales of tobacco to minors". More than half of the participants (60.5%) belonged to the age group 25-44 years, 61.3% graduated from high school or university. Most of the participants were smoker (39.2%) or ex-smoker (19.1%), and 41.7% of the participants was non-smoker. A greater proportion of the participants (76.2%) believed that smoking prevalence was greater than 40% among high school students. One in four (27.8%) adults did not know that tobacco control law bans sell of tobacco products to minors in Turkey. More than half of the participants (57.1%) ever witnessed tobacco sales to minors and 63.6% of them did not

Engagement in activism is related to several aspects of social development in adolescence and emerging adulthood. Therefore, it is important to examine the correlates of different forms of activism, such as feminist collective action, among all youth. However, previous research has not investigated young sexual-minority women's engagement with feminist collective action. This study examined predictors of college-aged heterosexual and sexual-minority women's commitment to and participation in feminist activism. Sexual orientation, number of years in college, social support, experiences with discrimination, and gender identity were tested as predictors of commitment to and participation in feminist activism with a sample of 280 college-aged women (173 heterosexuals and 107 sexual minorities). Similar predictors were related to both commitment to and participation in feminist activism. However, for sexual-minority women, but not heterosexual women, the number of years in college was correlated with participation in feminist activism. Young sexual-minority women reported more participation in feminist activism than did heterosexual women, even after controlling for social support, discrimination, and gender identity.

Full Text Available Background Minor head trauma accounts for 70% to 90% of all head traumas. Previous studies stated that minor head traumas were associated with 7% - 20% significant abnormal findings in brain computed tomography (CT-scans. Objectives The aim of this study was to reevaluate clinical criteria of taking brain CT scan in patients who suffered from minor head trauma. Patients and Methods We enrolled 680 patients presented to an academic trauma hospital with minor head trauma in a prospective manner. All participants underwent brain CT scan if they met the inclusion criteria and the results of scans were compared with clinical examination finding. Results Loss of consciousness (GCS drop or amnesia was markedly associated with abnormal brain CT scan (P < 0.05. Interestingly, we found 7 patients with normal clinical examination but significant abnormal brain CT scan. Conclusions According to the results of our study, we recommend that all patients with minor head trauma underwent brain CT scan in order not to miss any life-threatening head injuries.

To provide the appropriately diverse blood supply necessary to support alloimmunized and chronically transfused patients, minority donation recruitment programs have been implemented. This study investigated temporal changes in minority red blood cell (RBC) donation patterns in the United States. Data on donor race and ethnicity from 2006 through 2015, including the number of unique donors, collections, RBCs successfully donated, and average annual number of RBC donations per donor (donor fraction), were collected from eight US blood collectors. Minority donors were stratified into the following groups: Asian, black or African American, Hispanic or Latino, Native Indian or Alaska Native, Native Hawaiian or other Pacific Islander, white, multiracial/other, and no answer/not sure. Over the 10-year period, white donors annually constituted the majority of unique donors (range, 70.7%-73.9%), had the greatest proportion of collections (range, 76.1%-79.8%), and donated the greatest proportion of RBC units (range, 76.3%-80.2%). These donors also had the highest annual donor fraction (range, 1.82-1.91 units per donor). Black or African American donors annually constituted between 4.9 and 5.2% of all donors during the study period and donated between 4.0 and 4.3% of all RBC units. Linear regression analysis revealed decreasing numbers of donors, collections, and donated RBC units from white donors over time. Although the US population has diversified, and minority recruitment programs have been implemented, white donors constitute the majority of RBC donors and donations. Focused and effective efforts are needed to increase the proportion of minority donors. © 2017 AABB.

Full Text Available Throughout Europe and within various historical and socio-economic conditions, Slovaks have formed many enclaves and diasporas. In order to investigate common cultural and ethnic characteristics and/or differences between Slovaks in Slovakia and the various diasporas that they formed in relationship with majorities of their host countries, we suggest the usage of the cartographic method. Namely, during the 1997-1999 the Institute of Ethnology of the Slovakian Academy of Science used the cartographic method to analyze various complex questions relating to the traditional culture and ethnic history of many Slovakian minorities in the countries of Central Europe: in Poland, Ukraine, Romania and Hungary. The project was named Traditional Culture of Slovakian Minorities in Central Europe - the application of ethno-cartographic method in research and comparison of cultural manifestation. The project yield positive results and in 2000-2002 proceeded with yet another scientific project: Traditional Culture of Slovakian Minorities in Southeastern Europe - the application of the cartographic method in research and comparison of cultural manifestations once more, the data were obtained on the traditional folk culture of the Slovakian enclaves in Vojvodina and Croatia. The cartographic method used in both projects enabled researchers to document relevant data in a relatively short period of time. A solid foundation was created for a scientific synthesis of selected topics that deal with the traditional culture of Slovakian minorities in Central and Southeastern Europe, and its comparisons with the parent country culture. The cartographic method is widely used in Slovakia, in some 250 sites. Further, the scientific project of the Institute of Ethnology of the Slovakian Academy of Science named Traditional Culture of Slovakian Minorities in Central and Southern Europe as an integral part of their cultural inheritance (In between cultural stability and

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

Homogeneous Minor Actinide Transmutation in SFR: Neutronic Uncertainties Propagation with Depletion

International Nuclear Information System (INIS)

Buiron, L.; Plisson-Rieunier, D.

2015-01-01

In the frame of next generation fast reactor design, the minimisation of nuclear waste production is one of the key objectives for current R and D. Among the possibilities studied at CEA, minor actinides multi-recycling is the most promising industrial way achievable in the near-term. Two main management options are considered: - Multi-recycling in a homogeneous way (minor actinides diluted in the driver fuel). If this solution can help achieving high transmutation rates, the negative impact of minor actinides on safety coefficients allows only a small fraction of the total heavy mass to be loaded in the core (∼ few %). - Multi-recycling in heterogeneous way by means of Minor Actinide Bearing Blanket (MABB) located at the core periphery. This solution offers more flexibility than the previous one, allowing a total minor actinides decoupled management from the core fuel. As the impact on feedback coefficient is small larger initial minor actinide mass can be loaded in this configuration. Starting from a breakeven Sodium Fast Reactor designed jointly by CEA, Areva and EdF teams, the so called SFR V2B, transmutation performances have been studied in frame on the French fleet for both options and various specific isotopic management (all minor actinides, americium only, etc.). Using these results, a sensitivity study has been performed to assess neutronic uncertainties (i.e coming from cross section) on mass balance on the most attractive configurations. This work in based on a new implementation of sensitivity on concentration with depletion in the ERANOS code package. Uncertainties on isotopes masses at the end of irradiation using various variance-covariance is discussed. (authors)

High frequency characterization of Galfenol minor flux density loops

Directory of Open Access Journals (Sweden)

Ling Weng

2017-05-01

Full Text Available This paper presents the first measurement of ring-shaped Galfenol’s high frequency-dependent minor flux density loops. The frequencies of applied AC magnetic field are 1k, 5k, 10k, 50k, 100k, 200k, 300k, 500 kHz. The measurements show that the cycle area between the flux density and magnetic field curves increase with increasing frequency. High frequency-dependent characterization, including coercivity, specific power loss, residual induction, and maximum relative permeability are discussed. Minor loops for different max induction are also measured and discussed at the same frequency 100 kHz. Minor loops with the same max induction 0.05 T for different frequencies 50, 100, 200, 300, 400 kHz are measured and specific power loss are discussed.

Letter report: Minor component study for low-level radioactive waste glasses

1996-03-01

During the waste vitrification process, troublesome minor components in low-level radioactive waste streams could adversely affect either waste vitrification rate or melter life-time. Knowing the solubility limits for these minor components is important to determine pretreatment options for waste streams and glass formulation to prevent or to minimize these problems during the waste vitrification. A joint study between Pacific Northwest Laboratory and Rensselaer Polytechnic Institute has been conducted to determine minor component impacts in low-level nuclear waste glass

Minor Actinides Recycling in PWRs

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

2006-01-01

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

Aspartokinase in Lemna minor L

Science.gov (United States)

Wong, Kwan F.; Dennis, David T.

1973-01-01

The growth of Lemna minor was followed by means of frond number, fresh weight, and dry weight measurements in the presence of various amino acids at a concentration 0.25 mm. Lysine inhibited growth but not to the same extent as threonine and homoserine. Isoleucine was also an inhibitor of growth. In the presence of methionine there was some growth for 2 to 3 days, but by 5 days most of the plants appeared to be dead. When lysine and threonine were added together, there was no growth at all, and the plants were dead after 5 days. This effect of lysine + threonine could be reversed by adding methionine or homoserine to the growth medium. The isolated aspartokinase from Lemna showed inhibition by lysine and higher concentrations of threonine. When these amino acids were added together at low concentrations, there was a concerted inhibition of the aspartokinase. It is suggested that some effects of amino acids on the growth of L. minor can be explained on the basis of a concerted feedback control of aspartokinase. Images PMID:16658324

2015-06-01

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

2016-09-01

How do minority adolescents' personal acculturation preferences and peer norms of acculturation affect their social inclusion in school? Turkish and Moroccan minority adolescents (N = 681) reported their preferences for heritage culture maintenance, mainstream culture adoption, and their experiences of peer rejection as a key indicator of adjustment problems. Additionally, we aggregated peer acculturation norms of maintenance and adoption within ethnically diverse classrooms (N = 230 in 50 Belgian schools), distinguishing between co-ethnic (Turkish or Moroccan classmates only, N = 681) and cross-ethnic norms (also including N = 1,930 other classmates). Cross-ethnic peer-group norms (of adoption and maintenance) and co-ethnic norms (of maintenance, marginally) predicted minority experiences of peer rejection (controlling for ethnic composition). Moreover, misfit of minorities' own acculturation preferences with both cross-ethnic and co-ethnic peer-group norms was harmful. When cross-ethnic norms stressed adoption, 'integrationist' minority youth - who combined culture adoption with maintenance - experienced most peer rejection. Yet, when co-ethnic peers stressed maintenance, 'assimilationist' minority youth experienced most rejection. In conclusion, acculturation misfit with peer-group norms is a risk factor for minority inclusion in ethnically diverse environments. © 2016 The British Psychological Society.

Social Anxiety and Loneliness in Adults Who Solicit Minors Online.

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.

Minority Stress and Intimate Partner Violence Among Gay and Bisexual Men in Atlanta.

Science.gov (United States)

Stephenson, Rob; Finneran, Catherine

2017-07-01

Intimate partner violence (IPV) rates are disproportionately high among sexual minority populations. Few studies have examined the plausible relationship between minority stress and IPV among men who have sex with men. This study examines the associations between IPV and three indicators of minority stress: internalized homophobia, sexuality-based discrimination, and racism, in a large venue-based sample of gay and bisexual men from Atlanta, USA. Each of the minority stress measures was found to be significantly associated with increased odds of self-reporting any form of receipt of IPV. Significant associations were also identified between perpetration of IPV and minority stressors, with most types of IPV perpetration linked to internalized homophobia. This study confirms findings in a growing body of research supporting the relationship between minority stress and increased prevalence of IPV among men who have sex with men, and points to the need to address structural factors in IPV prevention programs for male-male couples.

Electronic cigarette sales to minors via the internet.

2015-03-01

Electronic cigarettes (e-cigarettes) entered the US market in 2007 and, with little regulatory oversight, grew into a $2-billion-a-year industry by 2013. The Centers for Disease Control and Prevention has reported a trend of increasing e-cigarette use among teens, with use rates doubling from 2011 to 2012. While several studies have documented that teens can and do buy cigarettes online, to our knowledge, no studies have yet examined age verification among Internet tobacco vendors selling e-cigarettes. To estimate the extent to which minors can successfully purchase e-cigarettes online and assess compliance with North Carolina's 2013 e-cigarette age-verification law. In this cross-sectional study conducted from February 2014 to June 2014, 11 nonsmoking minors aged 14 to 17 years made supervised e-cigarette purchase attempts from 98 Internet e-cigarette vendors. Purchase attempts were made at the University of North Carolina Internet Tobacco Vendors Study project offices using credit cards. Rate at which minors can successfully purchase e-cigarettes on the Internet. Minors successfully received deliveries of e-cigarettes from 76.5% of purchase attempts, with no attempts by delivery companies to verify their ages at delivery and 95% of delivered orders simply left at the door. All delivered packages came from shipping companies that, according to company policy or federal regulation, do not ship cigarettes to consumers. Of the total orders, 18 failed for reasons unrelated to age verification. Only 5 of the remaining 80 youth purchase attempts were rejected owing to age verification, resulting in a youth buy rate of 93.7%. None of the vendors complied with North Carolina's e-cigarette age-verification law. Minors are easily able to purchase e-cigarettes from the Internet because of an absence of age-verification measures used by Internet e-cigarette vendors. Federal law should require and enforce rigorous age verification for all e-cigarette sales as with the federal

Anatomy of the minor fissure: assessment with high-resolution CT and classification

International Nuclear Information System (INIS)

Ariyuerek, Macit O.; Yelgec, Selcuk N.; Guelsuen, Meltem; Karabulut, Nevzat

2002-01-01

The aims of this study were to investigate the anatomy of the minor fissure and its variations on high-resolution CT (HRCT) sections and to propose a detailed classification. The prospective study included 67 patients who were referred to CT for various indications. High-resolution CT examinations (1.5-mm collimation) were obtained through the region of the minor fissure. The CT scans were assessed for the presence, completeness, and configuration of the minor fissure. Various configurations of the minor fissure were classified into four major types, based on whether the highest portion of the middle lobe upper surface was medial (type I), lateral (type II), posterior (type III), or central (type IV). Minor fissure was identified in 65 (97%) of 67 patients, and absent in 2 (3%) cases. The fissure was incomplete in 35 (54%) of 65 patients. Type-I minor fissure is seen in 28 (43%) patients, type II in 22 (34%), type III in 5 (8%), and type IV in 2 (3%) patients. Because the majority of the fissure was absent in 8 (12%) of 35 patients with incomplete fissure, they were considered indeterminate. Comprehensive knowledge of the various configurations of the minor fissure is helpful in correct localization of a lesion and its extension. In equivocal cases, limited thin-section CT scans through the fissure delineate the anatomy more clearly and provide greater degree of precision in localizing pulmonary lesions. (orig.)

School-based victimization has short- and long-term implications for the health and academic lives of sexual minority students. This analysis assessed the prevalence and relative risk of school violence and bullying among sexual minority and heterosexual high school students. Youth Risk Behavior Survey data from 10 states and 10 large urban school districts that assessed sexual identity and had weighted data in the 2009 and/or 2011 cycle were combined to create two large population-based data sets, one containing state data and one containing district data. Prevalence of physical fighting, being threatened or injured with a weapon, weapon carrying, and being bullied on school property and not going to school because of safety concerns was calculated. Associations between these behaviors and sexual identity were identified. In the state data, sexual minority male students were at greater risk for being threatened or injured with a weapon, not going to school because of safety concerns and being bullied than heterosexual male students. Sexual minority female students were at greater risk than heterosexual female students for all five behaviors. In the district data, with one exception, sexual minority male and female students were at greater risk for all five behaviors than heterosexual students. Sexual minority students still routinely experience more school victimization than their heterosexual counterparts. The implementation of comprehensive, evidence-based programs and policies has the ability to reduce school violence and bullying, especially among sexual minority students.

The Primary objective of the proposed project is to apply and extend the latest advancements in LWR fuel management optimization to the design of advanced boiling water reactor (BWR) fuel assemblies specifically for the recycling of minor actinides (MAs). A top-level objective of the Advanced Fuel Cycle Systems Analysis program element of the DOE NERI program is to investigate spent fuel treatment and recycling options for current light water reactors (LWRs). Accordingly, this project targets to expand the traditional scope of nuclear fuel management optimization into the following two complementary specific objectives: (1) To develop a direct coupling between the pin-by-pin within-bundle loading control variables and core-wide (bundle-by-bundle) optimization objectives, (2) to extend the methodology developed to explicitly encompass control variables, objectives, and constraints designed to maximize minor actinide incineration in BWR bundles and cycles. The first specific objective is projected to 'uncover' dormant thermal margin made available by employing additional degrees of freedom within the optimization process, while the addition of minor actinides is expected to 'consume' some of the uncovered thermal margin. Therefore, a key underlying goal of this project is to effectively invest some of the uncovered thermal margin into achieving the primary objective.

Full Text Available Background This paper presents an attempt to determine the predictors of criminal thinking styles of minors, based on the theory of Glenn Walters. The construct which is the subject of this study, that is, criminal thinking, is treated as a factor that initiates and supports anti-social behaviour. It manifests itself in eight thinking styles (patterns: mollification, cut-off, entitlement, sentimentality, power orientation, cognitive indolence, discontinuity, and superoptimism. Participants and procedure The study involved 114 people: 65 boys and 49 girls. The research group consisted of minors – boys and girls who were referred, by order of the court, to Diagnostic and Consultation Family Centres to receive a psychological opinion, the purpose of which was to determine the degree of demoralisation of the minor. The study was also attended by the guardians of minors. A criterion for including a minor in this study was committing an offence. Results For each criminal thinking style, a forward stepwise regression analysis was conducted. Variables describing minors and mothers were included in the regression model. The aim of this approach is to identify the configuration of predictors of criminal thinking styles. In each of the models the coefficient of determination, R2, and  coefficients were calculated. Conclusions The predictors of criminal thinking styles identified by the regression analysis show the complexity and heterogeneity of factors contributing to the emergence of these cognitive distortions. Predictors include both properties conditioning the psychosocial functioning of mothers and factors determining the personality of a minor (sense of control, low empathy, low self-esteem. There is a noticeable influence of factors attributable to the mothers – variables derived from the environment (demanding, rejecting, inconsistent attitude.

Multilingual education for European minority languages: The Basque Country and Friesland

Gorter, Durk; Cenoz, Jasone

2011-12-01

Over the last three decades, regional minority languages in Europe have regained increased recognition and support. Their revitalisation is partly due to their being taught in schools. Multilingualism has special characteristics for speakers of minority languages and it poses unique challenges for learning minority languages. This article looks at the cases of Basque and Frisian, comparing and contrasting their similarities and differences. The educational system in the Basque Autonomous Community underwent an important transformation, starting in 1979 from a situation where less than 5 per cent of all teachers were capable of teaching through Basque. Today this figure has changed to more than 80 per cent. An innovative approach was chosen for teaching the minority language, Basque, alongside the dominant language, Spanish, and the international language, English. The outcome is a substantial increase in the proficiency in the minority language among the younger age groups. The decline of the minority language has thus been successfully reversed and one of the major challenges now is to uphold a sustainable educational system. By contrast, the Frisian language has fared less well in the Netherlands, where developments over the last 30 years have been much slower and the results more modest. Here policy-making for education and for language is caught in a continuous debate between a weak provincial level and a powerful central state level. Overall, multilingualism as a resource for individuals is valued for "bigger" languages such as English, French and German, but not for a "small" language such as Frisian. Nevertheless, a few trilingual experiments have been carried out in some schools in Friesland in teaching Frisian, Dutch and English. These experiments may also be instructive for other cases of minority languages of a "moderate strength". In the cases of both Basque and Frisian multilingualism is generally perceived as an important resource.

Effects of Geography on Mental Health Disparities on Sexual Minorities in New York City.

Gay and lesbian individuals have higher rates of psychological distress than do heterosexual individuals. The minority stress hypothesis attributes this disparity to adversity-related stress experienced by sexual minorities. In support of this idea, research in the U.S. has generally found that mental health disparities between sexual minorities and others are narrower in places where tolerance is relatively high. However, few studies have examined disparities between sexual minorities and others in neighborhoods where sexual minorities are most highly concentrated. Likewise, little research attention has been given to disparities for people who move to more tolerant places from less tolerant states and countries. Using data from the New York City Community Health Survey, we found some evidence that disparities between sexual minorities and others were lower in areas with higher concentrations of sexual minorities. However, disparities did not vary by the tolerance level of the state of birth among those born in the U.S. and were actually lower among those born in the least tolerant nations. These results complicate the idea that there is a dose-response relationship between tolerance and psychological distress among sexual minorities.

Parental consent requirements and privacy rights of minors: the contraceptive controversy.

Science.gov (United States)

1975-03-01

That the adult zone of privacy recognized by the Supreme Court during the past decade embraces access to contraceptives is suggested. 2 further questions are examined: 1) whether the right of children to have access to contraceptives is fundamental and 2) whether countervailing interests of parents and state should outweigh whatever interest the child has in obtaining contraceptives. More fundamentally, 3 complex issues relative to an analysis of minors' rights to obtain contraceptives are discussed: 1) the scope of the constitutional right of adults to obtain contraceptives remains uncertain; 2) courts have not yet articulated the special factors that determine how existing frameworks for analyzing the rights of adults are to be applied to minors; and 3) the question of minors' access to contraceptive involves a particularly complex mixture of the interests of minors, parents, and the state.

A lack of genetic markers impedes our understanding of the population biology of Lemna minor. Thus, the development of appropriate genetic markers for L. minor promises to be highly useful for population genetic studies and for addressing other life history questions regarding the species. • For the first time, we characterized nine polymorphic and 24 monomorphic chloroplast microsatellite markers in L. minor using DNA samples of 26 individuals sampled from five populations in Kashmir and of 17 individuals from three populations in Quebec. Initially, we designed 33 primer pairs, which were tested on genomic DNA from natural populations. Nine loci provided markers with two alleles. Based on genotyping of the chloroplast DNA fragments from 43 sampled individuals, we identified one haplotype in Quebec and 11 haplotypes in Kashmir, of which one occurs in 56% of the genotypes, one in 8%, and nine in 4%, respectively. There was a maximum of two alleles per locus. • These new chloroplast microsatellite markers for L. minor and haplotype distribution patterns indicate a complex phylogeographic history that merits further investigation.

Minor metals and renewable energy—Diversifying America’s energy sources

Solar photovoltaic (PV) and wind turbine technologies are projected to make up an increasing proportion of electricity generation capacity in the United States in the coming decades. By 2050, they will account for 36 percent (or 566 gigawatts) of capacity compared with about 11 percent (or 118 gigawatts) in 2016 (fig. 1; EIA, 2017). There are several different types of commercial solar PV and wind turbine technologies, and each type makes use of different minor metals. “Minor metal” is the term used for metals for which world production is small compared with the more widely produced base metals, and they are often produced as byproducts of the mining or processing of base metals. Minor metals used in renewable energy technologies often have complex supply chains, are often produced primarily outside of the United States, and are also used in many other applications. A larger amount of minor metals will be needed in the future to support the projected increases in solar PV and wind energy production capacity (Nassar and others, 2016).

Evolutionary Analysis of Minor Histocompatibility Genes In Hydra

KAUST Repository

Aalismail, Nojood

2016-05-01

Hydra is a simple freshwater solitary polyp used as a model system to study evolutionary aspects. The immune response of this organism has not been studied extensively and the immune response genes have not been identified and characterized. On the other hand, immune response has been investigated and genetic analysis has been initiated in other lower invertebrates. In the present study we took initiative to study the self/nonself recognition in hydra and its relation to the immune response. Moreover, performing phylogenetic analysis to look for annotated immune genes in hydra gave us a potential to analyze the expression of minor histocompatibility genes that have been shown to play a major role in grafting and transplantation in mammals. Here we obtained the cDNA library that shows expression of minor histocompatibility genes and confirmed that the annotated sequences in databases are actually present. In addition, grafting experiments suggested, although still preliminary, that homograft showed less rejection response than in heterograft. Involvement of possible minor histocompatibility gene orthologous in immune response was examined by qPCR.

Nurse practitioners are regularly faced with ethical and legal dilemmas when providing care to minors. Laws may not provide clear direction; there may even be conflicting precedents regarding the status of minors, particularly with regard to the juvenile justice system. This article reviews the status of minors' rights with regard to refusing or consenting to medical tests or treatments. Three cases from one author's (DPG) practice illustrate the issues involved.

National minorities and the question of the autonomy in the Carpathian Basin

Full Text Available The 21st century is the age of globa-lisation. It is also the time of minorities, identities moving back towards nationality-consciousness, minority rights and autonomies. These factors have a significant influence on the multinational state structures in both the developed and semi-peripheral areas of the world. The transformation of the unitarian centralised states and territorial systems carried out by devolutional, decentralised and region-regulatory processes as well as the development of the local councils and self-governing systems representing territorial autonomies of different levels indicate general tendencies. In the life of national minorities living in the territories of multinational states the mother tongue is the primary representative of national identity and serves as an increasingly powerful factor in the lives of national mi-norities.

A United States consensus group on the live donor concluded that minors (international guidelines reject this position. Recent United Network of Organ Sharing data show that minors serve as living donors, albeit infrequently. We examined the attitudes of US physicians toward minors as living donors. Four hundred members of the American Society of Transplantation and 160 physicians from the American Academy of Pediatrics Section of Nephrology or Bioethics were surveyed. The physicians were asked whether minors should be permitted to serve as living donors and how their opinion would change depending on the twins' zygosity, age, and increased waitlist time. One hundred seventy of 436 eligible participants (39%) returned surveys. Thirty-two and 39% of respondents would permit a kidney donation between 15-year-old fraternal and identical twins, respectively (P=NS). If the wait time increased from 1 to 6 years, willingness increased to 39% and 45%, respectively (P=NS). Pediatric bioethicists were the most reluctant to prohibit minors as living donors. Approximately one-third of US physicians would permit children to serve as donors. Lengthening the wait time is associated with a trend toward greater willingness to permit minor donations. Current policies that give preferential status for a deceased donor organ to minors may help minimize donations by their minor siblings. Nontransplant physicians need education about donor risks to ensure that donations are in the best interest of pediatric donors and recipients.

Divulgación: Offering Minority Communities Equal Opportunities Through Entrepreneurship

2014-09-01

Full Text Available A substantial body of research has been undertaken in recent years giving prominence to the additional and distinctive challenges faced by female entrepreneurs and by ethnic entrepreneurs. However, other groups of minority entrepreneurs have received relatively little attention and so remain underexplored within entrepreneurship literature. This article introduces some of these minority communities (Ex–Prisoners, Disabled People, Travellers/Gypsies, Grey and Gay and highlights the research opportunities that exist for entrepreneurship academics who might wish to analyse such ‘silent’ minorities. These communities are all relatively large in terms of population numbers, require tailored support to overcome distinctive economic, social and personal obstacles, and would benefit from critical appraisals of their circumstances.

2018-01-01

In the supervision literature, research on sexual orientation considerations often focuses on sexual minority supervisees and less often on their work with sexual minority clients. Yet both heterosexual and sexual minority supervisees serve sexual minority clients and may have different supervision needs. Twelve predoctoral interns from 12 APA-accredited counseling center internships were interviewed about how they made use of supervision for their work with a sexual minority client. The sample consisted of 6 heterosexual-identified supervisees and 6 supervisees who identified as lesbian, gay, or queer (LGQ). Data were analyzed using consensual qualitative research. All participants reported positive gains from supervision that carried over to their work with heterosexual and sexual minority clients, even when not all supervisors disclosed or discussed their own sexual orientation. Heterosexual supervisees used supervision to ensure that their heterosexuality does not interfere with an affirmative experience for their sexual minority client, whereas LGQ supervisees used supervision to explore differences in sexual identity development between themselves and their client to minimize the negative impact of overidentification. Thus, affirmative supervision may unfold with different foci depending on supervisees' sexual identity. Implications for training and supervision are discussed.

Strong social and legal norms in the United States discourage the overt expression of bias against ethnic and racial minorities, increasing the attributional ambiguity of Whites' positive behavior to ethnic minorities. Minorities who suspect that Whites' positive overtures toward minorities are motivated more by their fear of appearing racist than by egalitarian attitudes may regard positive feedback they receive from Whites as disingenuous. This may lead them to react to such feedback with feelings of uncertainty and threat. Three studies examined how suspicion of motives relates to ethnic minorities' responses to receiving positive feedback from a White peer or same-ethnicity peer (Experiment 1), to receiving feedback from a White peer that was positive or negative (Experiment 2), and to receiving positive feedback from a White peer who did or did not know their ethnicity (Experiment 3). As predicted, the more suspicious Latinas were of Whites' motives for behaving positively toward minorities in general, the more they regarded positive feedback from a White peer who knew their ethnicity as disingenuous and the more they reacted with cardiovascular reactivity characteristic of threat/avoidance, increased feelings of stress, heightened uncertainty, and decreased self-esteem. We discuss the implications for intergroup interactions of perceptions of Whites' motives for nonprejudiced behavior.

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

Self-stigma among concealable minorities in Hong Kong: conceptualization and unified measurement.

Self-stigma refers to the internalized stigma that individuals may have toward themselves as a result of their minority status. Not only can self-stigma dampen the mental health of individuals, it can deter them from seeking professional help lest disclosing their minority status lead to being shunned by service providers. No unified instrument has been developed to measure consistently self-stigma that could be applied to different concealable minority groups. The present study presented findings based on 4 studies on the development and validation of the Self-Stigma Scale, conducted in Hong Kong with community samples of mental health consumers, recent immigrants from Mainland China, and sexual minorities. Upon a series of validation procedures, a 9-item Self-Stigma Scale-Short Form was developed. Initial support on its reliability and construct validity (convergent and criterion validities) were found among 3 stigmatized groups. Utility of this unified measure was to establish an empirical basis upon which self-stigma of different concealable minority groups could be assessed under the same dimensions. Health-care professionals could make use of this short scale to assess potential self-stigmatization among concealable minorities, which may hamper their treatment process as well as their overall well-being.

Human Rhinovirus Diversity and Evolution: How Strange the Change from Major to Minor.

Science.gov (United States)

Lewis-Rogers, Nicole; Seger, Jon; Adler, Frederick R

2017-04-01

Rhinoviruses are the most common causes of the common cold. Their many distinct lineages fall into "major" and "minor" groups that use different cell surface receptors to enter host cells. Minor-group rhinoviruses are more immunogenic in laboratory studies, although their patterns of transmission and their cold symptoms are broadly similar to those of the major group. Here we present evolutionary evidence that minor-group viruses are also more immunogenic in humans. A key finding is that rates of amino acid substitutions at exposed sites in the capsid proteins VP2, VP3, and VP1 tend to be elevated in minor-group relative to major-group viruses, while rates at buried sites show no consistent differences. A reanalysis of historical virus watch data also indicates a higher immunogenicity of minor-group viruses, consistent with our findings about evolutionary rates at amino acid positions most directly exposed to immune surveillance. The increased immunogenicity and speed of evolution in minor-group lineages may contribute to the very large numbers of rhinovirus serotypes that coexist while differing in virulence. IMPORTANCE Most colds are caused by rhinoviruses (RVs). Those caused by a subset known as the minor-group members of rhinovirus species A (RV-A) are correlated with the inception and aggravation of asthma in at-risk populations. Genetically, minor-group viruses are similar to major-group RV-A, from which they were derived, although they tend to elicit stronger immune responses. Differences in their rates and patterns of molecular evolution should be highly relevant to their epidemiology. All RV-A strains show high rates of amino acid substitutions in the capsid proteins at exposed sites not previously identified as being immunogenic, and this increase is significantly greater in minor-group viruses. These findings will inform future studies of the recently discovered RV-C, which also appears to exacerbate asthma in adults and children. In addition, these

Harassment Due to Gender Nonconformity Mediates the Association Between Sexual Minority Identity and Depressive Symptoms.

Science.gov (United States)

Martin-Storey, Alexa; August, Elana G

2016-01-01

The visibility of a stigmatized identity is central in determining how individuals experience that identity. Sexual minority status (e.g., identifying as gay, lesbian, or bisexual) has traditionally been identified as a concealable stigma, compared with race/ethnicity or physical disability status. This conceptualization fails to recognize, however, the strong link between sexual minority status and a visible stigma: gender nonconformity. Gender nonconformity, or the perception that an individual fails to conform to gendered norms of behavior and appearance, is strongly stigmatized, and is popularly associated with sexual minority status. The hypothesis that harassment due to gender nonconformity mediates the association between sexual minority status and depressive symptoms was tested. Heterosexual and sexual minority-identified college and university students (N = 251) completed questionnaires regarding their sexual minority identity, experiences of harassment due to gender nonconformity, harassment due to sexual minority status, and depressive symptoms. A mediational model was supported, in which the association between sexual minority identity and depressive symptoms occurred via harassment due to gender nonconformity. Findings highlight harassment due to gender nonconformity as a possible mechanism for exploring variability in depressive symptoms among sexual minorities.

2018-03-01

Full Text Available Many children in Mexico are working in registered places where the sex trade is allowed, such as canteens, bars or nightclubs. This article, based on a qualitative methodology that includes in-depth interviews with owners of 73 centers dedicated to the sexual commerce in nine Mexican States, examines the prostitution of minors in these places towards the appreciations of the pimps, and concludes that the spread of a culture of bribery in the prostitution industry leads to the solidification of networks of complicity between the police and pimps leading to the prostitution of minors.

Mediating Factors Explaining the Association Between Sexual Minority Status and Dating Violence.

Science.gov (United States)

Martin-Storey, Alexa; Fromme, Kim

2017-08-01

Dating violence presents a serious threat for individual health and well-being. A growing body of literature suggests that starting in adolescence, individuals with sexual minority identities (e.g., individuals who identify as gay, lesbian, or bisexual) may be at an increased risk for dating violence compared with heterosexuals. Research has not, however, identified the mechanisms that explain this vulnerability. Using a diverse sample of young adults ( n = 2,474), the current study explored how minority stress theory, revictimization theory, sex of sexual partners, and risky sexual behavior explained differences in dating violence between sexual minority and heterosexual young adults. Initial analyses suggested higher rates of dating violence among individuals who identified as bisexual, and individuals who identified as gay or lesbian when compared with heterosexuals, and further found that these associations failed to differ across gender. When mediating and control variables were included in the analyses, however, the association between both sexual minority identities and higher levels of dating violence became nonsignificant. Of particular interest was the role of discrimination, which mediated the association between bisexual identity and dating violence. Other factors, including sex and number of sexual partners, alcohol use, and childhood maltreatment, were associated with higher rates of dating violence but did not significantly explain vulnerability among sexual minority individuals compared with their heterosexual peers. These findings suggest the importance of minority stress theory in explaining vulnerability to dating violence victimization among bisexuals in particular, and generally support the importance of sexual-minority specific variables in understanding risk for dating violence within this vulnerable population.

The minor immigrant and the effects of juvenile migration in Europe

2015-12-01

Full Text Available In the civil law and the international law, the minor immigrants are the new protagonists of migratory processes and constitute a fundamental subject. During the last decade, the presence of minors in the most important migration phenomenon has united migrations worldwide and the numbers increased significantly. There is no universal definition of the minor immigrant. This paper aims to describe the concept of minor immigrant, the effects of juvenile migration on the EU Member States and the measures to be taken in order to prevent the negative aspects and to reduce the human costs of migration processes. The method applied is the creation of placement and protection models able to comply with the obligations imposed by international conventions, model that is far from being considered adequate, since the convictions of the European Court of Human Rights prove the lack of practice in the field.

A differential equation approach to minor loops in the Jiles-Atherton hysteresis model

Jiles and Atherton, in a series of papers, present physically based differential equations for magnetization in ferromagnetic materials. however, if one directly solves their differential equations, the minor loops obtained can be negative slopes, which is a nonphysical behavior. Only one of their papers gives a method for obtaining minor loops, and the method does not use a differential equation, but requires a priori knowledge of the loop turning points in order to obtain a scale factor and offset which allow a portion of a major loop to serve as a portion of a minor one. In this paper, the reason for the failure of the differential equations to yield physical minor loops is explained, and a modified solution for minor loops is presented which retains the features of Jiles and Atherton's original minor loops, but only requires knowledge of the initial point on each portion of the loop to obtain the solution. This yields a general differential equation formulation for the Jiles-Atherton theory that can be used with circuit simulations having arbitrary excitations and initial conditions for ferromagnetic components

This study was undertaken to evaluate the toxicity of sediments collected from the Niger Delta (Nigeria) to Lemna minor, a sensitive aquatic weed regularly used for ecotoxicological studies. Also, the study wanted to determine if L. minor can be used as an effective bioassay organism by oil companies and chemical industries in Nigeria. Essentially, the experimental approach involved exposure of L. minor under standard laboratory conditions to sediments and toxicity is presented as percent inhibition of growth of L. minor cultures after 7 days. The result of the present study showed that there is differential toxicity among the sediments analyzed, and we found that for 0.25mg/ml of growth rate (%1) decreases in the order: SDOGN(42.6%) >SDWRR (33.7%)> SDALD (20.5%) >SDUGBO (17.1%) ? SDWRR were clorotic and had lost their roots, indicating the very high toxicity of the soluble organic contaminants in these sediments. Lemna minor proved to be a practical bioassay organism because the L. minor toxicity test is simple, sensitive and cost effective

Full Text Available The article discusses issues related to the provision of criminological security of minors at the national level. The Author analyzes the normative legal basis and main directions of activity of subjects of prevention of the violation of child rights in the Russian Federation. The Author believes that the current system of legal guarantees of criminological security of minors not fully meet modern requirements of protection of rights, freedoms and legitimate interests of adolescents. In particular, the legislation of the Russian Federation is largely focused on protecting the interests of disadvantaged segments of the population, including minors, being in socially dangerous position. It is proposed to improve the existing legislation through the adoption of a new federal law “The bases of the system of prevention of offences and security of minors”, which will be an important step towards building a legal state.

Full Text Available OBJECTIVE Identifying the violence suffered by the health team workers and their association with Burnout and minor psychiatric disorders. METHODS Cross-sectional study with 269 health team professionals of a public hospital in southern Brazil. Data were collected through the use of the Survey Questionnaire: Workplace Violence in the Health Sector, Maslach Inventory Burnout and Self-Report Questionnaire. RESULTS Workplace violence struck 63.2% of workers, prevailing mostly in women (p = 0.001, among nursing auxiliaries/technicians (p=0.014 and was associated with minor psychiatric disorders (p<0.05, as exposure to different forms of violence increased the chances of these disorders by 60% (CI 95%: 1.2-2.1. The three Burnout dimensions were also associated to violence at work (p<0.05. CONCLUSION Health workers experience violence in the workplace and this exposure is associated with Burnout symptoms and minor psychiatric disorders.

Patients with low National Institutes of Health Stroke Scale (NIHSS) scores are frequently excluded from thrombolysis, but more than 25% of them remain disabled. We sought to define a validated minor stroke definition to reduce the inappropriate treatment exclusion. From an outcome database, untreated patients with an NIHSS score of 5 or less presenting within a 4.5-hour window were identified and 3-month modified Rankin Scale (mRS) outcomes were analyzed according to individual isolated symptoms and total NIHSS scores. The validity of the following minor stroke definitions were assessed: (1) the National Institute of Neurological Disorders and Stroke Tissue Plasminogen Activator (NINDS-TPA) trials' definition, (2) the total NIHSS score, varying a cutoff point from 0 to 4, and (3) our proposed definition that included an NIHSS score = 0 or an NIHSS score = 1 on the items of level of consciousness (LOC), gaze, facial palsy, sensory, or dysarthria. Of 647 patients, 172 patients (26.6%) had a 3-month unfavorable outcome (mRS score 2-6). Favorable outcome was achieved in more than 80% of patients with an NIHSS score of 1 or less or with an isolated symptom on the LOC, gaze, facial palsy, sensory, or dysarthria item. In contrast, unfavorable outcome proportion was more than 25% in patients with an NIHSS score of 2 or more. When the NINDS-TPA trials' definition, our definition, or the definition of an NIHSS score of 1 or less were applied, more than 75% of patients with an unfavorable outcome were defined as a non-minor stroke and less than 15% of patients with an unfavorable outcome were defined as a minor stroke. Implementation of an optimal definition of minor stroke into thrombolysis decision-making process would decrease the unfavorable outcomes in patients with low NIHSS scores.
