Dynamics of Racial Residential Segregation and Gentrification in New York City

Racial residential segregation is interconnected with several other phenomena such as income inequalities, property values inequalities, and racial disparities in health and education. Furthermore, recent literature suggests the phenomenon of gentrification as a cause of perpetuation or increase of racial residential segregation in some American cities. In this paper, we analyze the dynamics of racial residential segregation for white, black, Asian, and Hispanic citizens in New York City in 1990, 2000, and 2010. It was possible to observe that segregation between white and Hispanic citizens and between white and Asian ones has grown, while segregation between white and black is relatively stable. Furthermore, we analyzed the per capita income and the Gini coefficient in each segregated zone, showing that the highest inequalities occur in the zones where there is an overlap of high-density zones of pair of races. Focusing on the changing of the density of population across the city during these 20 years, and by analyzing white and black people's segregation, our analysis reveals that a positive flux of white (black) people is associated with a substantial increase (decrease) of the property values, as compared with the city mean. Furthermore, by clustering the region with the higher density of black citizens, we measured the variation of area and displacement of the four most significant clusters from 1990 to 2010. The large displacements ( & AP; 1.6 k m ) observed for two of these clusters, namely, one in the neighborhood of Harlem and the other inside the borough of Brooklyn, led to the emergence of typically gentrified regions

Validation of Calprotectin As a Novel Biomarker For The Diagnosis of Pleural Effusion: a Multicentre Trial

Discriminating between malignant pleural effusion (MPE) and benign pleural effusion (BPE) remains difficult. Thus, novel and efficient biomarkers are required for the diagnosis of pleural effusion (PE). The aim of this study was to validate calprotectin as a diagnostic biomarker of PE in clinical settings. A total of 425 patients were recruited, and the pleural fluid samples collected had BPE in 223 cases (53.7%) or MPE in 137 patients (33%). The samples were all analysed following the same previously validated clinical laboratory protocols and methodology. Calprotectin levels ranged from 772.48 to 3,163.8 ng/mL (median: 1,939 ng/mL) in MPE, and 3,216-24,000 ng/mL in BPE (median: 9,209 ng/mL; p < 0.01), with an area under the curve of 0.848 [95% CI: 0.810-0.886]. For a cut-off value of </= 6,233.2 ng/mL, we found 96% sensitivity and 60% specificity, with a negative and positive predictive value, and negative and positive likelihood ratios of 96%, 57%, 0.06, and 2.4, respectively. Multivariate analysis showed that low calprotectin levels was a better discriminator of PE than any other variable [OR 28.76 (p < 0.0001)]. Our results confirm that calprotectin is a new and useful diagnostic biomarker in patients with PE of uncertain aetiology which has potential applications in clinical practice because it may be a good complement to cytological methods

Evaluation of silages of sweet potato vine

O presente trabalho teve como objetivo selecionar clones de batata-doce com potencial para uso na alimenta??o animal. O experimento foi conduzido em blocos ao acaso, com 11 clones e quatro repeti??es. Os clones avaliados fazem parte do banco de germoplasma da Universidade Federal dos Vales do Jequitinhonha e Mucuri, sendo: BD-06, BD-25, BD-15, BD-38, Cambraia, BD-31-TO, BD-67, BD-45, BD-42, BD-54 e a cultivar Brazl?ndia Rosada. Nas ramas coletadas do experimento foram avaliados o teor de mat?ria seca e as produtividades de massa verde e massa seca. Nas silagens de ramas foram avaliados o pH e os teores de mat?ria seca (MS), prote?na bruta (PB), fibra em detergente neutro (FDN), fibra em detergente ?cido (FDA), nutrientes digest?veis totais (NDT), f?sforo, c?lcio e s?dio. N?o houve diferen?a significativa para a produtividade de massa verde e de massa seca das ramas entre os clones de batata-doce. As silagens produzidas caracterizam-se como volumosos de boa qualidade, apresentando teores satisfat?rios de prote?na bruta (11,59%), FDN (31,98 a 39,68%), FDA (29,65 a 35,45%) e NDT (62,90 a 66,91%), comprovando o potencial de utiliza??o das ramas da batata-doce na forma de silagem.Funda??o de Amparo ?

The experiment was carried out in a randomized block design with four replications. Eleven clones BD-06, BD-25, BD-15, BD-38, Cambraia, BD-31-TO, BD-67, BD-45, BD-42, BD-54 and the cultivar Brazl?ndia Rosada belonging to germplasm bank of the Federal University of Vales do Jequitinhonha and Mucuri (UFVJM) were evaluated. We estimated the dry matter content and the productivity of green and dry mass of the vine. The traits pH, dry matter, crude protein phosphorus, calcium and sodium were estimated in the evaluation of silages quality. There was no significant difference in productivity of green mass and dry mass among the clones of sweet potato. The obtained silages had sufficient levels of crude protein (11.59%), neutral detergent fiber (31.98 to 39.68%), acid detergent fiber (29.65 to 35.45%) and total digestible nutrients (62.90 to 66.91%) proving the potential use of the sweet potato vine as silage in animal feeding

Agronomic performance and genetic parameters of sweet potato genotypes

O presente trabalho teve por objetivo avaliar o desempenho agron?mico em gen?tipos de batata-doce e estimar par?metros gen?ticos. O experimento foi composto por 65 variedades (clones do banco de germoplasma de batata-doce da Universidade Federal dos Vales do Jequitinhonha e Mucuri), instalado num delineamento em blocos ao acaso com tr?s repeti??es e 15 plantas por parcela. Foram avaliadas a produtividade de massa verde das ramas (MV), produtividade total das ra?zes (PT), peso m?dio das ra?zes totais (PMT), produtividade de ra?zes comerciais (PC), peso m?dio das ra?zes comerciais (PMC), formato das ra?zes (FORM) e resist?ncia a insetos (RI). Considerando-se os ganhos de sele??o estimados para estas caracter?sticas, infere-se que a sele??o de clones pode levar a progressos gen?ticos signifcativos. Os caracteres PT, PMT, PC, e PMC est?o positivamente correlacionados, logo, a sele??o em qualquer um deles acarreta ganhos gen?ticos nos demais. A sele??o para produ??o de ra?zes pode ser conduzida no car?ter PT, pois sua avalia??o ? mais simples e correlaciona-se com a produ??o comercial, que ? de maior import?ncia. A sele??o no car?ter MV promove aumento nas caracter?sticas PMT e PMC e n?o causa efeitos nas demais. Para a maioria das caracter?sticas houve predomin?ncia dos efeitos ambientais sobre os gen?ticos. Os gen?tipos BD-15, BD-42 e BD-67 apresentaram melhor desempenho agron?mico.Funda??o de Amparo ?

The experiment consisted of 65 varieties (clones) of the sweet potato germplasm bank from the Federal University of the Jequitinhonha and Mucuri Valley, installed in the design of randomized blocks with three replications and 15 plants per plot. Were evaluated green mass of branches (MV), total productivity of roots (PT), average weight of total roots (PMT), commercial yield (PC), the average weight of marketable roots (PMC), shape of roots (FORM) and insect resistance (IR). Considering the gains of selection for these characteristics, we infer that clone selection can lead to significant genetic progress. The characters PT, PMT, PC and PMC are positively correlated, so selecting any of them carries genetic gains in others. Selection for root production can be conducted in the character PT because its evaluation is simpler and correlates with the commercial production, which is of utmost importance. The selection promotes increases in MV character in PMC and PMT and causes no effects in others. For most traits were prevalent environmental effects on genetic. The BD-15, BD-42 and BD-67 genotypes showed better agronomic performance

We studied the morphological characters of kale genotypes originated from the germplasm bank of UFVJM, the genetic divergence among the genotypes and the importance of these characters in the estimates of divergence. The experiment was carried out in the Department of Horticulture of UFVJM, Diamantina, Minas Gerais state, Brazil, using the randomized complete block design with four replications and thirty genotypes, consisting of five plants. Forty-four traits were evaluated on each plant for morphological evaluations. Some genotypes showed high genetic divergence, such as the genotypes UFLA-6 and 24-UFVJM, which were the most divergent compared to the others. Most of the genotypes, however, were similar to each other. It was also observed that there are important characteristics that can be used in the estimation of divergence

Selection of lettuce genotypes for protected cultivation: genetic divergence and importance of characters

Os objetivos deste trabalho foram selecionar gen?tipos de alface com potencial para cultivo em ambiente protegido; selecionar gen?tipos divergentes geneticamente para integrar programas de melhoramento; comparar t?cnicas multivariadas a fim de se ter uma interpreta??o mais precisa dos resultados; verificar a relev?ncia dos caracteres avaliados para a diverg?ncia gen?tica; e determinar os caracteres mais importantes na avalia??o de gen?tipos de alface. Utilizou-se o delineamento em blocos casualizados, com 15 gen?tipos, quatro repeti??es e 15 plantas por parcela. O experimento foi conduzido em ambiente protegido e avaliou-se a altura das plantas, di?metro da cabe?a, circunfer?ncia da cabe?a, mat?ria fresca da parte a?rea, mat?ria fresca comercial da parte a?rea, mat?ria fresca da raiz, mat?ria seca comercial da parte a?rea, mat?ria seca da raiz e n?mero de folhas comerciais. Os gen?tipos foram classificados em quatro grupos pelo m?todo Tocher. Foram indicados para uso em cultivo protegido e em programas de melhoramento para obten??o de cultivares adaptadas a essas condi??es, as cultivares 'Regina 500'e 'Vit?ria de S. Ant?o' (grupo I), 'Black Seed Simpson' e 'L?via' (grupo II), 'Branca Boston' (grupo III) e 'Romana Bal?o' (grupo IV). Embora a contribui??o relativa da circunfer?ncia para a diverg?ncia seja apenas 0,50%, todas as caracter?sticas avaliadas foram importantes no estudo da diverg?ncia gen?tica. De acordo com o estudo da correla??o genot?pica, a avalia??o da caracter?stica massa fresca da parte a?rea pode substituir a avalia??o das caracter?sticas massa fresca e massa seca comercial da parte a?rea em um processo de sele??o, reduzindo tempo e custo em um programa de melhoramento.Funda??o de Amparo ?

Fifteen genotypes were studied in a randomized block design with four replications and 15 plants per plot. The experiment was carried out in protected environments and the following traits were evaluated: plant height, head diameter; head circumference; fresh matter of heads; marketable fresh matter of heads; root fresh matter; dry matter of commercial heads; dry matter of roots and number of commercial leaves. The genotypes were classified in four groups by Tocher's method. The genotypes that should preferably be used in protected environment and in breeding programs were 'Regina 500' and 'Vit?ria de S. Ant?o', from group I; 'Black Seed Simpson' and 'L?via' from group II; 'Branca Boston' from group III and 'Romana Bal?o' from group IV. Although the relative contribution of the head circumference is only 0.50%, all traits were important in the study of genetic diversity. According to the genotypic correlation study, the assessment of the fresh mass characteristic of the aerial part can substitute the evaluation of commercial fresh and dry mass of the aerial part in the selection process, reducing the time and cost in a breeding program

The descriptive epidemiology of DSM-IV Adult ADHD in the World Health Organization World Mental Health Surveys

We previously reported on the cross-national epidemiology of ADHD from the first 10 countries in the WHO World Mental Health (WMH) Surveys. The current report expands those previous findings to the 20 nationally or regionally representative WMH surveys that have now collected data on adult ADHD. The Composite International Diagnostic Interview (CIDI) was administered to 26,744 respondents in these surveys in high-, upper-middle-, and low-/lower-middle-income countries (68.5% mean response rate). Current DSM-IV/CIDI adult ADHD prevalence averaged 2.8% across surveys and was higher in high (3.6%)- and upper-middle (3.0%)- than low-/lower-middle (1.4%)-income countries. Conditional prevalence of current ADHD averaged 57.0% among childhood cases and 41.1% among childhood subthreshold cases. Adult ADHD was significantly related to being male, previously married, and low education. Adult ADHD was highly comorbid with DSM-IV/CIDI anxiety, mood, behavior, and substance disorders and significantly associated with role impairments (days out of role, impaired cognition, and social interactions) when controlling for comorbidities. Treatment seeking was low in all countries and targeted largely to comorbid conditions rather than to ADHD. These results show that adult ADHD is prevalent, seriously impairing, and highly comorbid but vastly under-recognized and undertreated across countries and cultures
