Abstract: little is known about transmission and drug resistance of tuberculosis (tb) in bauru, state of s?o paulo. the objective of this study was to evaluate risk factors for transmission of mycobacterium tuberculosis strains in this area. strains were collected from patients attended at ambulatory services in the region and susceptibility towards the main first line antibiotics was determined and fingerprinting performed. a total of 57 strains were submitted to susceptibility testing: 23 (42.6%) were resistant to at least one drug while 3 (13%) were resistant against both rifampicin and isoniazide. resistant strains had been isolated from patients that had not (n = 13) or had (n = 9) previously been submitted to anti-tb treatment, demonstrating a preoccupying high level of primary resistance in the context of the study. all strains were submitted to is6110 restriction fragment length polymorphism (is6110-rflp) and double repetitive element pcr (dre-pcr). using is6110-rflp, 26.3% of the strains were clustered and one cluster of 3 patients included 2 hiv-infected individuals that had been hospitalized together during 16 days; clustering of strains of patients from the hospital was however not higher than that of patients attended at health posts. according to dre-pcr, 55.3% belonged to a cluster, confirming the larger discriminatory power of is6110-rflp when compared to dre-pcr, that should therefore be used as a screening procedure only. no clinical, epidemiological or microbiological characteristics were associated with clustering so risk factors for transmission of tb could not be defined in the present study.

Abstract: fingerprinting of mycobacterium tuberculosis strains from tuberculosis (tb) patients attended in community health centers (chcs) of rio de janeiro was performed to verify possible risk factors for tb transmission. a prospective community-based study was performed during the period of july 1996 to december 1996 by collecting sputum samples of 489 patients in 11 different chcs in four different planning areas (aps) of the city. bacteriological, clinical, and epidemiological information was collected and m. tuberculosis genotypes defined after restriction fragment length polymorphism (is6110-rflp) and double repetitive element (dre) fingerprinting of rflp-clustered cases. risk factors for tb transmission were looked for using three levels of cluster stringency. among 349 (71%) positive cultures obtained, is6110-rflp typing could be performed on strains from 153 different patients. when using identity of rflp patterns as cluster definition, 49 (32%) of the strains belonged to a cluster and none of the clinical or epidemiologic characteristics was associated with higher clustering levels. however, higher clustering level was observed in the ap including the central region of the city when compared to others. this strongly suggests that more recent transmission occurs in that area and this may be related with higher incidence of tb and hiv in this region.
Brazil is a country of “balangand s” (swaying ornaments) in French imaginary O Brasil é um país de “balangand s” no imaginário francês

Discursos Fotográficos , 2006,
Abstract: This article explains how the French have built a distorted image of Brazil in their imaginary. Such image was built long before, based on French travelers reports and even Brazilian historians. For the French, Brazil is a country of balangand s, plenty of festivals, bronzed female mulattoes, carnival and football. In 2005, there was the Year of Brazil in France and the event organizers insisted on exhibiting stereotyped images (clichés) of Brazil.Este artigo mostra como os franceses construíram uma imagem distorcida do Brasil em seu imaginário. Essa imagem foi construída, desde os primórdios, a partir de relatos de viajantes franceses e mesmo de historiadores brasileiros. Para os franceses, o Brasil é um país de balangand s, muita festa, gente alegre, sol o ano inteiro, mulatas bronzeadas, carnaval e futebol. Em 2005, aconteceu o Ano do Brasil na Fran a e a organiza o do evento insistiu em exibir imagens estereotipadas (clichês) do Brasil.

Abstract: we performed spoligotyping and 12-mycobacterial interspersed repetitive unit-variable number tandem repeats (miru-vntrs) typing to characterise mycobacterium bovis isolates collected from tissue samples of bovines with lesions suggestive for tuberculosis during slaughter inspection procedures in abattoirs in brazil. high-quality genotypes were obtained with both procedures for 61 isolates that were obtained from 185 bovine tissue samples and all of these isolates were identified as m. bovis by conventional identification procedures. on the basis of the spoligotyping, 53 isolates were grouped into nine clusters and the remaining eight isolates were unique types, resulting in 17 spoligotypes. the majority of the brazilian m. bovis isolates displayed spoligotype patterns that have been previously observed in strains isolated from cattle in other countries. miru-vntr typing produced 16 distinct genotypes, with 53 isolates forming eight of the groups, and individual isolates with unique vntr profiles forming the remaining eight groups. the allelic diversity of each vntr locus was calculated and only two of the 12-miru-vntr loci presented scores with either a moderate (0.4, miru16) or high (0.6, miru26) discriminatory index (h). both typing methods produced similar discriminatory indexes (spoligotyping h = 0.85; miru-vntr h = 0.86) and the combination of the two methods increased the h value to 0.94, resulting in 29 distinct patterns. these results confirm that spoligotyping and vntr analysis are valuable tools for studying the molecular epidemiology of m. bovis infections in brazil.
World knowledge and image reading: a study about intertextuality on publicity photography Conhecimento de mundo e leitura de imagem: um estudo sobre a intertextualidade na fotografia publicitária
Maranúbia Pereira Barbosa-Doiron
Discursos Fotográficos , 2010,
Abstract: This study aims to analyse the content of intertextuality ob publicity photography. According to textual linguistic theoretical premises, intertextuality is understood as the relation – direct or indirect – between texts, and its use as a resource on publicity has been rising substantially. In order to produce meaning effects on advertisement and its persuasive feature, it is necessary a common knowledge among producers and readers. The producer hopes that the reader’s world knowledge can provide basis to understand not only the explicit message on the text surface, but also and mainly the implicit and implied. On Louis Vuitton publicity campaign studied here, the world knowledge is fundamental to develop a critic and profound review. Este estudo tem como proposta analisar a intertextualidade em fotografias publicitárias. A intertextualidade, segundo pressupostos teóricos da Linguística Textual, é entendida como a rela o, direta ou indireta, entre os textos, e se constitui em um recurso cada vez mais utilizado em publicidade. Para que a propaganda, de natureza essencialmente persuasiva, produza efeitos de sentido, é necessário que haja uma boa parcela de conhecimento partilhado entre produtor e leitor. O produtor espera que o conhecimento de mundo do leitor possa lhe proporcionar embasamento para que compreenda n o apenas o dito explícito na superfície textual, mas, também, e sobretudo, o implícito e o subentendido. Nas imagens da campanha publicitária aqui analisada, da grife francesa Louis Vuitton, o conhecimento de mundo se revela leitura crítica e aprofundada.
Bumiputera-Controlled Companies: Performance Evaluation Using A Non-Parametric Approach

International Journal of Economics and Finance , 2010, DOI: 10.5539/ijef.v2n2p178
Abstract: This study examines the effects of crisis and post-crisis periods on the performance of Bumiputera-controlled companies in Malaysia. A sample of 33 Bumiputera-controlled companies listed on Bursa Malaysia is considered over the period 1996 to 2005. ROE is used as a performance measure and Wilcoxon Signed Ranks Test is used to justify our argument. Results indicate that Bumiputera-controlled companies suffered in both short run and long run due to the financial crisis.

Mergers and Acquisitions: Some Empirical Evidence on Performance, Financial Characteristics and Firm Sustainability
Maran Marimuthu
International Journal of Business and Management , 2009, DOI: 10.5539/ijbm.v3n10p8
Abstract: The study examines the performance and financial characteristics of non-financial companies (low and high sales growth companies) that were involved in mergers and acquisitions in Malaysia. Capital gains were used to measure the companies’ performance over a period of two years and profitability measures (ROE, EPS, dividends payout, gearing ratio, PE ratio) were incorporated in the study. Paired sample testing and independent t-test analyses were adopted. The study reveals that there is no significant difference in terms of performance between low and high sales growth of companies in the presence of economic shock. However, high sales growth companies which are small in size seem to be more vulnerable to economic shock compared to low sales growth companies. In terms of financial characteristics, statistically, there are no significant differences between the two groups but the low sales growth companies (which are large in size) tend to register higher returns to shareholders.
