    Malignant hyperthermia (MH) is a pharmacogenetic disease triggered in susceptible individuals by the administration of volatile halogenated anesthetics and/or succinylcholine, leading to the development of a hypermetabolic crisis, which is caused by abnormal release of Ca2+ from the sarcoplasmic reticulum, through the Ca2+ release channel ryanodine receptor 1 (RyR1). Mutations in the RYR1 gene are associated with MH in the majority of susceptible families. Genetic screening of a 5-generation Brazilian family with a history of MH-related deaths and a previous MH diagnosis by the caffeine halothane contracture test (CHCT) in some individuals was performed using restriction and sequencing analysis. A novel missense mutation, Gly4935Ser, was found in an important functional and conserved locus of this gene, the transmembrane region of RyR1. In this family, 2 MH-susceptible individuals previously diagnosed with CHCT carry this novel mutation and another 24 not previously diagnosed members also carry it. However, this same mutation was not found in another MH-susceptible individual whose CHCT was positive to the test with caffeine but not to the test with halothane. None of the 5 MH normal individuals of the family, previously diagnosed by CHCT, carry this mutation, nor do 100 controls from control Brazilian and USA populations. The Gly4932Ser variant is a candidate mutation for MH, based on its co-segregation with disease phenotype, absence among controls and its location within the protein.

    The transformed opportunity structure individuals have experienced over the course of the 20th century has not only changed family life, but also led to increased educational requirements, higher expectations of social mobility in the labor market, and overall perceived prospects of a healthier...... life. Moreover, presence of generational transmission of family formation behavior such as cohabitation, age at first marriage and childbearing has been widely documented. Thus, it has become more appropriate to approach family life events in a non-linear manner by emphasizing the existence of various...... family formation pathways, and to study these pathways from a generational point of view. Drawing on a life course perspective and by means of rich multigenerational longitudinal data combined with data from the Danish central population registers, this study examines multigenerational transmission...

    The study of the intergenerational transmission of fertility has a long history in demography, but until now research has focused primarily on parents' influence on their children's fertility patterns and has largely overlooked the possible influence of other kin. This study examines the transmission of fertility patterns from parents, grandparents, uncles, and aunts, using event history models to determine the risk of first, second, and third births. Swedish register data are used to study the 1970-82 birth cohorts. The findings indicate strong associations between the fertility of index persons and that of their parents, and also independent associations between the completed fertility of index persons and that of their grandparents and parents' siblings. The results suggest that, when examining background effects in fertility research, it is relevant to take a multigenerational perspective and to consider the characteristics of extended kin.

    Roda, Ricardo H; Schindler, Alice B; Blackstone, Craig

    2017-11-01

    Autosomal recessive KIF1A missense mutations cause hereditary spastic paraplegia (HSP) type SPG30, while recessive truncations lead to sensory and autonomic neuropathy (HSN2C) and many de novo missense mutations are associated with cognitive impairment. Here, we describe family members across three generations with pure HSP. A heterozygous p.Ser69Leu KIF1A mutation segregates with those afflicted. The same variant was previously reported in a Finnish father and son with pure HSP as well as four members of a Sicilian kindred with more intrafamilial phenotypic variability. This further validates the pathogenicity of the p.Ser69Leu mutation and suggests that it may represent a mutation hot spot.

    Purpose To evaluate phenotypic expressions of speech sound disorder (SSD) in multigenerational families with evidence of familial forms of SSD. Method Members of five multigenerational families (N = 36) produced rapid sequences of monosyllables and disyllables and tapped computer keys with repetitive and alternating movements. Results Measures of repetitive and alternating motor speed were correlated within and between the two motor systems. Repetitive and alternating motor speeds increased in children and decreased in adults as a function of age. In two families with children who had severe speech deficits consistent with disrupted praxis, slowed alternating, but not repetitive, oral movements characterized most of the affected children and adults with a history of SSD, and slowed alternating hand movements were seen in some of the biologically related participants as well. Conclusion Results are consistent with a familial motor-based SSD subtype with incomplete penetrance, motivating new clinical questions about motor-based intervention not only in the oral but also the limb system.

    Full Text Available Childhood apraxia of speech (CAS is a severe and socially debilitating form of speech sound disorder with suspected genetic involvement, but the genetic etiology is not yet well understood. Very few known or putative causal genes have been identified to date, e.g., FOXP2 and BCL11A. Building a knowledge base of the genetic etiology of CAS will make it possible to identify infants at genetic risk and motivate the development of effective very early intervention programs. We investigated the genetic etiology of CAS in two large multigenerational families with familial CAS. Complementary genomic methods included Markov chain Monte Carlo linkage analysis, copy-number analysis, identity-by-descent sharing, and exome sequencing with variant filtering. No overlaps in regions with positive evidence of linkage between the two families were found. In one family, linkage analysis detected two chromosomal regions of interest, 5p15.1-p14.1, and 17p13.1-q11.1, inherited separately from the two founders. Single-point linkage analysis of selected variants identified CDH18 as a primary gene of interest and additionally, MYO10, NIPBL, GLP2R, NCOR1, FLCN, SMCR8, NEK8, and ANKRD12, possibly with additive effects. Linkage analysis in the second family detected five regions with LOD scores approaching the highest values possible in the family. A gene of interest was C4orf21 (ZGRF1 on 4q25-q28.2. Evidence for previously described causal copy-number variations and validated or suspected genes was not found. Results are consistent with a heterogeneous CAS etiology, as is expected in many neurogenic disorders. Future studies will investigate genome variants in these and other families with CAS.

    Ectodermal dysplasia is a highly heterogeneous group of disorders that variably affect the derivatives of the ectoderm, primarily skin, hair, nails and teeth. TP63, itself mutated in ectodermal dysplasia, links many other ectodermal dysplasia disease genes through a regulatory network that maintains the balance between proliferation and differentiation of the epidermis and other ectodermal derivatives. The ectodermal knockout phenotype of five mouse genes that regulate and/or are regulated by TP63 (Irf6, Ikkα, Ripk4, Stratifin, and Kdf1) is strikingly similar and involves abnormal balance towards proliferation at the expense of differentiation, but only the first three have corresponding ectodermal phenotypes in humans. We describe a multigenerational Saudi family with an autosomal dominant form of hypohidrotic ectodermal dysplasia in which positional mapping and exome sequencing identified a novel variant in KDF1 that fully segregates with the phenotype. The recapitulation of the phenotype we observe in this family by the Kdf1-/- mouse suggests a causal role played by the KDF1 variant.

    Nonsyndromic cleft lip with or without cleft palate (CL/P) is a common craniofacial developmental defect. Recent segregation analyses have suggested that major genes play a role in the etiology of CL/P. Linkage to 22 candidate genes was tested in 11 multigenerational families with CL/P, and 21 of these candidates were excluded. APOC2, 19q13.1, which is linked to the proto-oncogene BCL3, gave suggestive evidence for linkage to CL/P. The study was expanded to include a total of 39 multigenerational CL/P families. Linkage was tested in all families, using anonymous marker, D19S178, and intragenic markers in BCL3 and APOC2. Linkage was tested under two models, autosomal dominant with reduced penetrance and affecteds-only model. Both models showed evidence of heterogeneity, with 43% of families linked at zero recombination to BCL3 when marker data from BCL3 and APOC2 were included. A maximum multipoint LOD score of 7.00 at BCL3 was found among the 17 families that had posterior probabilities {ge}50% in favor of linkage. The transmission disequilibrium test provided additional evidence for linkage with the 3 allele of BCL3 more often transmitted to affected children. These results suggest that BCL3, or a nearby gene, plays a role in the etiology of CL/P in some families. 39 refs., 8 figs., 4 tabs.

    Recent theories regarding the pathophysiology of bipolar disorder suggest contributions of both neurodevelopmental and neurodegenerative processes. While structural neuroimaging studies indicate disease-associated neuroanatomical alterations, the behavioural correlates of these alterations have not been well characterized. Here, we investigated multi-generational families genetically enriched for bipolar disorder to: (i) characterize neurobehavioural correlates of neuroanatomical measures implicated in the pathophysiology of bipolar disorder; (ii) identify brain–behaviour associations that differ between diagnostic groups; (iii) identify neurocognitive traits that show evidence of accelerated ageing specifically in subjects with bipolar disorder; and (iv) identify brain–behaviour correlations that differ across the age span. Structural neuroimages and multi-dimensional assessments of temperament and neurocognition were acquired from 527 (153 bipolar disorder and 374 non-bipolar disorder) adults aged 18–87 years in 26 families with heavy genetic loading for bipolar disorder. We used linear regression models to identify significant brain–behaviour associations and test whether brain–behaviour relationships differed: (i) between diagnostic groups; and (ii) as a function of age. We found that total cortical and ventricular volume had the greatest number of significant behavioural associations, and included correlations with measures from multiple cognitive domains, particularly declarative and working memory and executive function. Cortical thickness measures, in contrast, showed more specific associations with declarative memory, letter fluency and processing speed tasks. While the majority of brain–behaviour relationships were similar across diagnostic groups, increased cortical thickness in ventrolateral prefrontal and parietal cortical regions was associated with better declarative memory only in bipolar disorder subjects, and not in non

    Schizophrenia is a serious mental illness, involving disruptions in thought and behavior, with a worldwide prevalence of about one percent. Although highly heritable, much of the genetic liability of schizophrenia is yet to be explained. We searched for susceptibility loci in multiplex, multigenerational families affected by schizophrenia, targeting protein-altering variation with in silico predicted functional effects. Exome sequencing was performed on 136 samples from eight European-American families, including 23 individuals diagnosed with schizophrenia or schizoaffective disorder. In total, 11,878 non-synonymous variants from 6,396 genes were tested for their association with schizophrenia spectrum disorders. Pathway enrichment analyses were conducted on gene-based test results, protein-protein interaction (PPI) networks, and epistatic effects. Using a significance threshold of FDR < 0.1, association was detected for rs10941112 (p = 2.1 × 10 -5 ; q-value = 0.073) in AMACR, a gene involved in fatty acid metabolism and previously implicated in schizophrenia, with significant cis effects on gene expression (p = 5.5 × 10 -4 ), including brain tissue data from the Genotype-Tissue Expression project (minimum p = 6.0 × 10 -5 ). A second SNP, rs10378 located in TMEM176A, also shows risk effects in the exome data (p = 2.8 × 10 -5 ; q-value = 0.073). PPIs among our top gene-based association results (p < 0.05; n = 359 genes) reveal significant enrichment of genes involved in NCAM-mediated neurite outgrowth (p = 3.0 × 10 -5 ), while exome-wide SNP-SNP interaction effects for rs10941112 and rs10378 indicate a potential role for kinase-mediated signaling involved in memory and learning. In conclusion, these association results implicate AMACR and TMEM176A in schizophrenia risk, whose effects may be modulated by genes involved in synaptic plasticity and neurocognitive performance. © 2017 Wiley Periodicals, Inc.

    Adiponectin, an adipose-specific protein, is negatively associated with adiposity, insulin sensitivity, and diabetes. Very few studies have examined the role of heredity in the regulation of adiponectin and its association with body fat among individuals of African heritage. Thus, we measured fasting serum adiponectin levels by radioimmunoassay and body composition by dual-energy x-ray absorptiometry (DEXA) in 402 individuals aged 18 to 103 years belonging to 7 multigenerational families of African heritage in the relatively homogeneous island population of Tobago. Heritability of adiponectin was 33.2% (P genetic factors are a significant source of interindividual differences in circulating adiponectin among Afro-Caribbeans. Adiponectin may serve as a promising quantitative intermediate trait in studies designed to map the genes underlying diabetes and obesity in this population.

    Very few studies have comprehensively defined the genetic and environmental influences on body fat storage in the arms and legs and their association with diabetes, especially in families of African heritage. We analyzed body fat distribution by dual-energy x-ray absorptiometry (percentage total fat, percentage trunk fat, percentage arm fat, and percentage leg fat) and fasting serum glucose in 471 individuals (mean age, 43 years) from 8 multigenerational Afro-Caribbean families (mean family size = 51; 3535 relative pairs). Diabetes was inversely associated with percentage leg fat (P = .009) and, to some extent, positively associated with percentage arm fat independent of age, sex, and body size (P = .08), but not with anthropometric or dual-energy x-ray absorptiometric measures of total and central adiposity. Furthermore, percentage leg fat was inversely, whereas percentage arm fat was positively, associated with body mass index, waist circumference, and serum glucose (P Genetic correlation (rho(G)) between arm and leg fat was -0.61 (P genetic influences. This study provides new evidence for a strong genetic and sex contribution to upper and lower body fat, with relatively little covariation between these traits due to shared genes. Our findings also suggest that, in this population, leg fat is associated with diabetes independent of overall adiposity.

    Patients with bipolar disorder from the US have more early-onset illness and a greater familial loading for psychiatric problems than those from the Netherlands or Germany (abbreviated here as Europe). We hypothesized that these regional differences in illness burden would extend to the patients siblings. Outpatients with bipolar disorder gave consent for participation in a treatment outcome network and for filling out detailed questionnaires. This included a family history of unipolar depression, bipolar disorder, suicide attempt, alcohol abuse/dependence, drug abuse/dependence, and "other" illness elicited for the patients' grandparents, parents, spouses, offspring, and siblings. Problems in the siblings were examined as a function of parental and grandparental problems and the patients' adverse illness characteristics or poor prognosis factors (PPFs). Each problem in the siblings was significantly (pUS than in those from Europe. In the US, problems in the parents and grandparents were almost uniformly associated with the same problems in the siblings, and sibling problems were related to the number of PPFs observed in the patients. Family history was based on patient report. Increased familial loading for psychiatric problems extends through 4 generations of patients with bipolar disorder from the US compared to Europe, and appears to "breed true" into the siblings of the patients. In addition to early onset, a variety of PPFs are associated with the burden of psychiatric problems in the patients' siblings and offspring. Greater attention to the multigenerational prevalence of illness in patients from the US is indicated. Copyright © 2016 Elsevier B.V. All rights reserved.

    The m.1555A>G mtDNA variant causes maternally inherited deafness, but the reasons for the highly variable clinical penetrance are not known. Exome sequencing identified a heterozygous start loss mutation in SSBP1, encoding the single stranded binding protein 1 (SSBP1), segregating with hearing loss in a multi-generational family transmitting m.1555A>G, associated with mtDNA depletion and multiple deletions in skeletal muscle. The SSBP1 mutation reduced steady state SSBP1 levels leading to a perturbation of mtDNA metabolism, likely compounding the intra-mitochondrial translation defect due to m.1555A>G in a tissue-specific manner. This family demonstrates the importance of rare trans-acting genetic nuclear modifiers in the clinical expression of mtDNA disease. © The Author (2017).

    Distal hereditary motor neuropathy (dHMN) causes distal-predominant weakness without prominent sensory loss. Myosin heavy chain disorders most commonly result in distal myopathy and cardiomyopathy with or without hearing loss, but a complex phenotype with dHMN, myopathy, hoarseness, and hearing loss was reported in a Korean family with a c.2822G>T mutation in MYH14. In this study we report phenotypic features in a North American family with the c.2822G>T in MYH14. Clinical and molecular characterization was performed in a large, 6-generation, Caucasian family with MYH14 dHMN. A total of 11 affected and 7 unaffected individuals were evaluated and showed varying age of onset and severity of weakness. Genotypic concordance was confirmed with molecular analysis.

    Full Text Available Diane A Caporale, Erica E SwensonDepartment of Biology, University of Wisconsin – Stevens Point, Stevens Point, WI, USAAbstract: Breast and lung cancer are two of the most common malignancies in the United States, causing approximately 40,000 and 160,000 deaths each year, respectively. Over 80% of hereditary breast cancer cases are due to mutations in two breast cancer predisposition genes, BRCA1 and BRCA2. These are tumor-suppressor genes associated with DNA repair. Since the discovery of these two genes in the mid-1990s, several other breast cancer predisposition genes have been identified, such as the CHEK2 gene encoding a regulator of BRCA1. Recently, studies have begun investigating the roles of BRCA1 and BRCA2 gene expression in lung cancer. We conducted a family-based case study that included a bloodline of Italian heritage with several cases of breast cancer and associated cancers (prostate and stomach through multiple generations and on a nonblood relative of Scottish/Irish descent who was consecutively diagnosed with breast and lung cancer. Cancer history and environmental risk factors were recorded for each family member. To investigate possible genetic risks, we screened for mutations in specific hypervariable regions of the BRCA1, BRCA2, and CHEK2 genes. DNA was extracted and isolated from the individuals' hair follicles and cheek cells. Polymerase chain reaction (PCR, allele-specific PCR, and DNA sequencing were performed to identify and verify the presence or absence of mutations in these regions. Genotypes of several family members were determined and carriers of mutations were identified. Here we report for the first time the occurrence of two different BRCA2 frameshift mutations within the same family. Specifically, three Italian family members were found to be carriers of the BRCA2-c.2808_2811delACAA (3036delACAA mutation, a 4-nucleotide deletion in exon 11, which is a truncated mutation that causes deleterious function of

    We aimed to provide unbiased estimates of familial risk and heritability of social anxiety disorder (SAD) and avoidant personality disorder (AVPD). We identified 18 399 individuals diagnosed with SAD and 2673 with AVPD in the Swedish National Patient Register between 1997 and 2009. Risks (odds ratios; OR) for SAD in all biological and non-biological relatives of probands, compared to relatives of unaffected individuals were calculated. We also estimated the risks for AVPD in relatives of probands with SAD. The risk for SAD among relatives of SAD probands increased proportionally to the degree of genetic relatedness. The risks for first-degree relatives [OR 4.74, 95% confidence interval (CI) 4.28-5.25] were significantly higher than for second-degree and third-degree relatives. Second-degree relatives (OR 2.30, 95% CI 2.01-2.63) had significantly higher risk than third-degree relatives (OR 1.72, 95% CI 1.52-1.94). Relatives at similar genetic distances had similar risks for SAD, despite different degrees of shared environment. Heritability was estimated to be approximately 56%. There were no significant sex differences in the familial patterns. The risk of AVPD in relatives of SAD probands was significantly elevated, even after excluding individuals with both diagnoses (first-degree OR 3.54, second-degree OR 2.20, third-degree OR 1.62). Non-biological relatives (spouses/partners) also had elevated risks for both SAD (OR 4.01) and AVPD (OR 3.85). SAD clusters in families primarily due to genetic factors. SAD and AVPD are aetiologically related and may represent different expressions of the same vulnerability. The strong marital concordance observed in SAD/AVPD may indicate assortative mating but the exact mechanisms and implications require further investigation.

    Full Text Available OBJECTIVE: To analyze the food intake of sugarcane workers' family members. METHODS: The food intake of 159 family members of sugarcane workers from Gameleira, Pernambuco, Brazilian Northeast, was investigated by directly weighing the foods on three non-consecutive days. The percent risk of inadequate macro- and micronutrient intakes was analyzed according to the Reference Dietary Intakes. The macronutrients were analyzed in relation to acceptable distribution intervals. The energy consumed from the various food groups was expressed as a ratio of the total energy intake. RESULTS: The median intake of carbohydrates and proteins remained above the Estimated Average Requirement, and all age groups presented a low risk of inadequate carbohydrate and protein intakes. The median intakes of riboflavin, niacin, thiamin, and iron remained above the Estimated Average Requirement for all age groups, but children aged 1-3 years presented a high percent risk of inadequate iron intake. All age groups presented high percent risk of inadequate zinc, calcium, vitamin A, and vitamin C intakes. Grains and derivatives had a greater participation in the total energy intake, especially in men aged 19-30 years. The group "milk and dairy products" had a greater participation in the diet of children aged 1-3 years. CONCLUSION: The low percent risk of inadequate carbohydrate and protein intakes in all age groups was opposed to the high risk of inadequate mineral and vitamin intakes, making the population vulnerable to nutritional disorders caused by excess macronutrient intake and inadequate micronutrient intake.

It uses data from 1,157 municipalities that have foster care services. The methodology takes into account the data collection of 2,624 Brazilian centers and 36,929 children and adolescents in care. The growing number of children/adolescents in care is in line with the increase in population size: 8.4 per small city; 60 per large city and 602.4 per metropolis. With respect to care residence in a different municipality there are varying indices: 12.4% in metropolises and 33.6% in small cities, revealing the absence of centers close to family units in the smaller communities. Regarding the activities promoted together with families, it was seen that there are still units that do not perform any activities, which runs contrary to Brazilian law. It is clear that policies for the child/adolescent in foster care centers need to consider the capacity of the municipality in accordance with population size to implement support actions for families to assist in family reintegration.

    Purpose To describe a novel polymorphism in the γD-crystallin (CRYGD) gene in a Brazilian family with congenital cataract. Methods A Brazilian four-generation family was analyzed. The proband had bilateral lamellar cataract and the phenotypes were classified by slit lamp examination. Genomic DNA was extracted from peripheral blood and coding regions and intron/exon boundaries of the αA-crystallin (CRYAA), γC-crystallin (CRYGC), and CRYGD genes were amplified by polymerase chain reaction and directly sequenced. Results Sequencing of the coding regions of CRYGD showed the presence of a heterozygous A→G transversion at c.401 position, which results in the substitution of a tyrosine to a cysteine (Y134C). The polymorphism was identified in three individuals, two affected and one unaffected. Conclusions A novel rare variant in CRYGD (Y134C) was detected in a Brazilian family with congenital cataract. Because there is no segregation between the substitution and the phenotypes in this family, other genetic alterations are likely to be present. PMID:21866214

    To culturally adapt the Family Quality of Life Scale to the Brazilian Portuguese version and evaluate the instrument reliability and family quality of life of those who have children with hearing loss. The process of cultural adaptation of the scale followed the steps of the Guidelines for the Process of Cross-Cultural Adaptation of Self-Report Measure. It was conducted in three stages: translation, back translation, and application in a pilot sample, as a way to check the comprehension difficulties of the items. After it had been completed, it was administered to 41 families who have children with hearing loss and, with their results, the quality of life and reliability were analyzed based on the Cronbach's alpha statistical test. In the first version (translation), among the 25 items, there were differences between the translators only in four items; after the corrections, the second version was done (back translation), in which other four more differences were found. Finally, after the final corrections, the last version was developed and used in the pilot sample without differences. Thus, it was applied to families with deaf children, who believe to be satisfied as to their quality of life. The Cronbach's alpha test found that the scale shows a satisfactory reliability. The Brazilian Portuguese version of the Family Quality of Life Scale is a tool of easy use and satisfactory reliability. The families are satisfied with their family quality of life.

    This article seeks to describe the viewpoint of purchasing food products from family farmers, analyzing their performance within the new guidelines of the Brazilian School Nutrition Program (PNAE). It is a critical assessment based on a review of the literature and the official data provided by the National Fund for the Development of Education/Ministry of Education relating to 2010. The program budget in 2010 was approximately R$2.5 billion and attended 45.6 million children, adolescents and adults. From the total amount, R$150,397,052.68 was allocated for the purchase of agricultural products from family farmers. In Brazil, 47.4% of the local councils acquired food products from family farmers for the Brazilian School Nutrition Program and the purchase percentage was, on average, 22.7%. Given the nature of recent legislation, other aspects should be explored in order to strengthen the compliance with the regulations in different Brazilian contexts and thus contribute both to local economic development and the provision of school meals which fulfill the principles of a healthy and adequate diet.

  1. Influence of Control and Family Management in the Indebtedness of Brazilian Open Business: a Quantitative Study

    2014-01-01

    Full Text Available This research investigated the influence of the family on the debt of Brazilian open business companies. Although there is a vast national and international literature on capital structure, there are still doubts on the importance of family in business management. In Brazil, due to the large number of family businesses, it is even more evident the need to investigate the issue. The studied population was composed of companies listed on the BM&FBovespa, in 2010, and the final sample consisted of 356 companies. Six years were analyzed (2004-2009, in a total of 2,136 observations. The results show that the studied companies that are familiar or that have family management have become less indebted than others. This result is in accordance with national and international studies, according to which family firms tend to be more conservative in their investments, seeking to use more equity than third party capital.

    Malignant hyperthermia (MH) is an autosomal dominant disorder that predisposes susceptible individuals to a potentially life-threatening crisis when exposed to commonly used anesthetics. Mutations in the skeletal muscle calcium release channel, ryanodine receptor (RYR1) are associated with MH in over 50% of affected families. Linkage analysis of the RYR1 gene region at 19q13 was performed in a large Brazilian family and a distinct disease co-segregating haplotype was revealed in the majority of members with diagnosis of MH. Subsequent sequencing of RYR1 mutational hot spots revealed a nucleotide substitution of C to T at position 7062, causing a novel amino acid change from Arg2355 to Cys associated with MH in the family. Haplotype analysis of the RYR1 gene area at 19q13 in the family with multiple MH members is an important tool in identification of genetic cause underlying this disease.

    Amelogenesis imperfecta (AI) is a genetically heterogeneous group of diseases that result in defective development of tooth enamel. Mutations in several enamel proteins and proteinases have been associated with AI. The object of this study was to evaluate evidence of etiology for the six major candidate gene loci in two Brazilian families with AI. Genomic DNA was obtained from family members and all exons and exon-intron boundaries of the ENAM, AMBN, AMELX, MMP20, KLK4 and Amelotin gene were amplified and sequenced. Each family was also evaluated for linkage to chromosome regions known to contain genes important in enamel development. The present study indicates that the AI in these two families is not caused by any of the known loci for AI or any of the major candidate genes proposed in the literature. These findings indicate extensive genetic heterogeneity for non-syndromic AI.

    This study describes and evaluates the influence of income on the percentage of food expenditures away from home for Brazilian families. Food acquisition data from the National Household Budget Survey conducted from 2002 to 2003 (POF 2002/2003) by the Brazilian Institute of Geography and Statistics (IBGE) or National Census Bureau was used in the analysis. Information on food-and-drink expenditures away from home was analyzed. The influence of income on the share of food purchased away from home in the household budget, adjusted for socio-demographic variables, was analyzed through elasticity coefficients estimated in multiple linear regression. Food purchased away from home accounted for 21% of total food expenditures by Brazilian households. A 10% increase in income increased the share of food purchased away from home by 3%. Income elasticity was high, especially for the lowest income families. The results demonstrate an important influence of income on food expenditures away from home, and higher income is associated with a greater share of food purchased away from home.

    Iden, Ronald

    The multigenerational workforce presents a critical challenge for business managers, and each generation has different expectations. A human resource management study of organizations with more than 500 employees reported 58% of the managers experiencing conflict between younger and older workers. The purpose of this single case study was to explore the multigenerational strategies used by 3 managers from a Franklin County, Ohio manufacturing facility with a population size of 6 participants. The conceptual framework for this study was built upon generational theory and cohort group theory. The data were collected through face-to-face semistructured interviews, company documents, and a reflexive journal. Member checking was completed to strengthen the credibility and trustworthiness of the interpretation of participants' responses. A modified van Kaam method enabled separation of themes following the coding of data. Four themes emerged from the data: (a) required multigenerational managerial skills, (b) generational cohort differences, (c) most effective multigenerational management strategies, and (d) least effective multigenerational management strategies. Findings from this study may contribute to social change through better understanding, acceptance, and appreciation of the primary generations in the workforce, and, in turn, improve community relationships.

    This paper considers the support networks of older people in populations with a preponderance of multigenerational households and examines the most vulnerable network types in terms of loneliness and isolation. Current common typologies of support networks may not be sensitive to differences within and between different cultures. This paper uses cross-sectional data drawn from 590 elders (Gujaratis, Punjabis and Sylhetis) living in the United Kingdom and South Asia. Six variables were used in K-means cluster analysis to establish a new network typology. Two logistic regression models using loneliness and isolation as dependent variables assessed the contribution of the new network type to wellbeing. Four support networks were identified: 'Multigenerational Households: Older Integrated Networks', 'Multigenerational Households: Younger Family Networks', 'Family and Friends Integrated Networks' and 'Non-kin Restricted Networks'. Older South Asians with 'Non-kin Restricted Networks' were more likely to be lonely and isolated compared to others. Using network typologies developed with individualistically oriented cultures, distributions are skewed towards more robust network types and could underestimate the support needs of older people from familistic cultures, who may be isolated and lonely and with limited informal sources of help. The new typology identifies different network types within multigenerational households, identifies a greater proportion of older people with vulnerable networks and could positively contribute to service planning.

  9. Professional versus family management in Brazilian fashion retail companies: exploring value-investors’ perceptions

    Clarice Secches Kogut

    Full Text Available Abstract Regarding the debate on which sort of management - professional or family administration - would more effectively run businesses, this paper discusses the advantages and shortcomings of family and professional management from a theoretical and a practitioner’s viewpoint. The study aims at contributing to our understanding about the superiority that either type of management might have delivering long-term performance and value creation to shareholders. Six investors from top value investment funds were interviewed regarding the management of seven fashion retail Brazilian companies. Data analysis revealed that investors do not prefer either type of management - family or professional - when they make investments. Instead, they do look for specific characteristics and patterns of behavior in a CEO, which resemble Selznick’s (1957 definition of an institutional leader. Finally, the paper suggests a new path of research for scholars (relating old institutionalism and professionalism and practical guidelines for each type of management (family or professional, offering, therefore, an academic as well as a practical contribution.

    To study the association between aspects of mental health and the family context with tobacco experimentation and consumption among Brazilian schoolchildren. A cross-sectional study using data from the National Survey of Schoolchildren's Health in Brazil conducted on 109,104 schoolchildren from the ninth year of elementary school, day scholars in public and private schools in all Brazilian state capitals and the Federal District. Descriptive analysis of variables, bivariate and multivariate analyses were performed with logistic regression estimates, adjusted for socioeconomic variables, obtaining the odds ratio (OR) and 95% confidence interval (95%CI). Among the participants, 52.2% were female. Twenty point nine percent of the students reported having experimented with cigarettes at least once. Adolescents who experienced more often feelings of loneliness (OR: 2.07; 95%CI: 1.98-2.16), difficulty sleeping (OR: 2.37; 95%CI: 2.52-2.48) and lower social interaction (OR: 1.27; 95%CI: 1.26-1.32), were more likely to smoke, regardless of socioeconomic status. The schoolchildren of parents or caregivers (OR: 2.39; 95%CI: 2.29-2.49) who did not know what their children did in their free time (OR: 1.52; 95%CI: 1.46-1.59) were associated with more frequent cigarette smoking. An association was seen between aspects of mental health and the family context with the experimentation and consumption of tobacco in adolescents enrolled in the study in Brazil. These associations are independent of school type, sex and skin colour. It is important that programmes for the prevention of tobacco use in adolescence emphasise these findings.

    2000-11-01

    Full Text Available Familial hypercholesterolemia (FH is a metabolic disorder inherited as an autosomal dominant trait characterized by an increased plasma low-density lipoprotein (LDL level. The disease is caused by several different mutations in the LDL receptor gene. Although early identification of individuals carrying the defective gene could be useful in reducing the risk of atherosclerosis and myocardial infarction, the techniques available for determining the number of the functional LDL receptor molecules are difficult to carry out and expensive. Polymorphisms associated with this gene may be used for unequivocal diagnosis of FH in several populations. The aim of our study was to evaluate the genotype distribution and relative allele frequencies of three polymorphisms of the LDL receptor gene, HincII1773 (exon 12, AvaII (exon 13 and PvuII (intron 15, in 50 unrelated Brazilian individuals with a diagnosis of heterozygous FH and in 130 normolipidemic controls. Genomic DNA was extracted from blood leukocytes by a modified salting-out method. The polymorphisms were detected by PCR-RFLP. The FH subjects showed a higher frequency of A+A+ (AvaII, H+H+ (HincII1773 and P1P1 (PvuII homozygous genotypes when compared to the control group (P<0.05. In addition, FH probands presented a high frequency of A+ (0.58, H+ (0.61 and P1 (0.78 alleles when compared to normolipidemic individuals (0.45, 0.45 and 0.64, respectively. The strong association observed between these alleles and FH suggests that AvaII, HincII1773 and PvuII polymorphisms could be useful to monitor the inheritance of FH in Brazilian families.

    Full Text Available The Basel Accord imposes a regulatory minimum capital requirement for banks to maintain their liquidity and are less susceptible to shocks from the interconnection of the financial system. Banks need to manage the dynamics of funding and applications in order to avoid excess or shortage of monetary resources, they are exposed to risks such as credit risk and liquidity risk. Credit risk is the risk that the counterparty in the transaction does not honor its obligation. Liquidity risk is the risk of the financial institution become unable to honor its obligations. The debt ratio of Brazilian families grew during the period analyzed, and a high level of debt increases the chances of default and expose financial institutions to credit risk and liquidity risk. The objective of this article is to analyze the relationship between the Basel index released by the banks and the high level of household debt in Brazil. The study used data available at the time series management system (SMS of the Central Bank of Brazil, which cover the period from January 2005 to December 2013, the following variables: Basel index, debt, inflation IPCA, Selic rate , Delinquency in SPC through an ARCH model (Autoregressive Conditional Heteroskedasticity. The results demonstrate that the Basel index, and the household debt levels have negative correlation, which makes the two vary in opposite directions. We can compare the model results for the Brazilian financial system with what was observed in the US market, as, for example, the perspective of authors who point to the beginning of the financial crisis of 2008, as a result of high indebtedness of American families in the business of mortgages.

    Academic medicine is a unique work environment, one of the few where members of four different generations regularly interact and where multigenerational teams are key to fulfilling its missions, particularly education. This can lead to increased creativity, but also to intergenerational conflict, since each generation has different values and expectations. The authors describe multigenerational challenges confronted at the University of California, Davis, School of Medicine, and that school's responses to them. These challenges include issues related to work hours, workload, compensation, evaluation for advancement, recruitment and retention, and attendance at required meetings. Awareness of the different generational qualities and values allowed the school of medicine to identify the multigenerational origin of many of these ongoing issues and challenges and to plan appropriate solutions within the Office of Academic Affairs. These include policy changes related to work-life balance, utilizing multiple faculty tracks with different roles, allowing part-time faculty appointments, creating a variety of faculty development programs geared toward different generational needs (which utilize flexible modules, menus of options, and alternative technologies for presentation), defining appropriate reward and incentives through compensations plans, and creating peer-reviewed awards. The authors conclude that these efforts mitigate conflict, promote diversity, and allow multigenerational teams to function more effectively and creatively in education, research, and clinical care. Ongoing evaluation will further refine this approach.

    This article analyzes data regarding cases of domestic violence treated by the emergency services through the following: the sociodemographic characteristics of the people who were treated; the events themselves; the evolution of care (from childhood to old age by gender); and the factors that differentiate cases of domestic violence compared to those committed by non-family members. Data from 24 Brazilian state capitals and the Federal District were analyzed, comprising 86 emergency services: a total of 4,893 individuals were surveyed. Of those people who were treated by emergency services, 26.6% suffered domestic violence: 40.0% were children/adolescents, 57.2% were adults and 2.8% were elderly. The adjusted model, which compared victims of violence committed by other family members with those who were not family members, showed that males were less likely to suffer from domestic violence; those that had fewer years of education were at increased risk; and that women were more likely to commit domestic violence compared to the category of "both genders". This study reinforces the fact that health sector professionals need to be able to deal with domestic violence by providing support, performing good practices, abiding by care protocols, taking care of injuries, and facilitating access to other services.

    This paper presents Project InterActions, a series of 5-week workshops in which very young learners (4- to 7-year-old children) and their parents come together to build and program a personally meaningful robotic project in the context of a multigenerational robotics-based community of practice. The goal of these family workshops is to teach both parents and children about the mechanical and programming aspects involved in robotics, as well as to initiate them in a learning trajectory with and about technology. Results from this project address different ways in which parents and children learn together and provide insights into how to develop educational interventions that would educate parents, as well as children, in new domains of knowledge and skills such as robotics and new technologies.

    To investigate gene mutations in familial form (FALS) and sporadic form (SALS) of amyotrophic lateral sclerosis (ALS) in a highly miscegenated population. Frequencies of mutations in the C9orfF72, TARDBP, SOD1, FUS and VAPB genes were investigated in a cohort of FALS (n = 39) and SALS (n = 189) subjects from the Research Centre of the University of São Paulo School of Medicine. All patients were subjected to C9orf72 and TARDBP analyses. SOD1, FUS and VAPB were also evaluated in FALS subjects. Mutations were identified in FALS (61.3%) and SALS (5.3%) patients. Mutations in C9orf72 (12.8%, >45 GGGGCC hexanucleotide repeats), VAPB (43.6%, P56S) and SOD1 (7.7%, L145S) were identified in FALS subjects. Pathogenic C9orf72 expansions (2.64%) were identified in some SALS patients. Similar changes of TARDBP were found in SALS (2.64%) but not in FALS subjects. No FUS mutations were seen in any FALS subjects. TARDBP and C9orf72 mutations in this cohort were similar to those found in other centres worldwide. VAPB mutation (P56S) was highly prevalent in Brazilian FALS patients.

    Full Text Available Cockayne syndrome (CS is an autosomal recessive disorder characterized by dwarfism, growth deficiency, neurological deterioration, skin photosensitivity and a characteristic progressive facial appearance. In the present study we report the first Brazilian CS family in which diagnosis was confirmed by the demonstration of decreased RNA synthesis in cultured fibroblasts exposed to UV-C radiation. Despite the progressive course of the disease and the unavailability of an effective treatment, diagnosis may be very important for the benefits to be gained by the afflicted family from genetic counseling and/or prenatal diagnosis.

    To evaluate the internal reliability and validity of the Brazilian Portuguese version of the Family Questionnaire among families of schizophrenia outpatients. The main studies about the family environment of schizophrenia patients are related to the concept of Expressed Emotion. There is currently no instrument to evaluate this concept in Brazil that is easily applicable and comparable with studies from other countries. Methodological and cross-sectional research design. A convenience sample of 130 relatives of schizophrenia outpatients was selected. The translation and cultural adaptation of the instrument involved experts in mental health and experts in the German language and included back translation, semantic evaluation of items and pretesting of the instrument with 30 relatives of schizophrenia outpatients. The psychometric properties of the instrument were studied with another 100 relatives, which fulfilled the requirements for the Brazilian Portuguese version of the instrument. The psychometric properties of the instrument were assessed by construct validity (using an analysis of its key components, comparisons between distinct groups-convergent validity with the Antonovsky's Sense of Coherence Scale) and reliability (checking the internal consistency of its items and its test-retest reproducibility). The analysis of main components confirmed dimensionality patterns that were comparable between the original and adapted versions. In two domains of the instrument, critical comments and emotional over-involvement had moderate and significant correlations, respectively, with Antonovsky's Sense of Coherence Scale, appropriate values of Cronbach's alpha and strong and significant correlations, respectively, in test-retest reproducibility. We observed significant differences between distinct groups of parents in the category of emotional over-involvement. We conclude that the Portuguese-adapted version of the Family Questionnaire is valid and reliable for the

      Gorlin-Goltz syndrome (GGS) seems to be unusual in black persons. The authors present an Afro-Brazilian family case report of GGS. The main complaint of the index case was a painless swelling of the left mandible, which was diagnosed as an odontogenic keratocyst. Further classical features of the Syndrome were present in this patient. Other two family members were diagnosed as cases of GGS and one of them presented 11 clinical findings characteristic of the syndrome. From the three cases reported, two of them presented five major diagnostic criteria for the GGS, and the diagnosis was only made because of an oral complaint. This case series emphasizes the importance of carefully examining the patient and close relatives for signs of GGS, even if they belong to an ethnic group in which this diagnosis is unusual. © 2014 Special Care Dentistry Association and Wiley Periodicals, Inc.

      2008-01-01

      For the first time in history, radiologic science (RS) workplaces consist of 4 generational cohorts. As each cohort possess their own attitudes, values, work habits, and expectations, motivating a generational diverse workplace is challenging. Through the understanding of generational differences, managers are better able to accommodate individual as well as generational needs and help create a more productive and higher performing workplace. The purpose of this paper is to assist managers in the understanding and utilization of generational differences to effectively motivate staff in an RS workplace. Generational cohorts will be defined and discussed along with an in-depth discussion on each of the generations performing in today's RS workplace. Motivators and how they impact the different generational cohorts will be addressed along with how to best motivate a multigenerational RS workplace.

      To compare clinical characteristics of bipolar disorder (BD) in patients with and without a family history of mood disorders (FHMD) in a large sample from the Brazilian Research Network of Bipolar Disorders. Four-hundred eighty-eight DSM-IV BD patients participating in the Brazilian Research Network of Bipolar Disorders were included. Participants were divided between those with FHMD (n=230) and without FHMD (n=258). We compared these two groups on demographic and clinical variables and performed a logistic regression to identify which variables were most strongly associated with positive family history of mood disorders. BD patients with FHMD presented with significantly higher lifetime prevalence of any anxiety disorder, obsessive-compulsive disorder, social phobia, substance abuse, and were more likely to present history of suicide attempts, family history of suicide attempts and suicide, and more psychiatric hospitalizations than BD patients without FHMD. Logistic regression showed that the variables most strongly associated with a positive FHMD were any comorbid anxiety disorder, comorbid substance abuse, and family history of suicide. Cross-sectional study and verification of FHMD by indirect information. BD patients with FHMD differ from BD patients without FHMD in rates of comorbid anxiety disorder and substance abuse, number of hospitalizations and suicide attempts. As FHMD is routinely assessed in clinical practice, these findings may help to identify patients at risk for particular manifestations of BD and may point to a common, genetically determined neurobiological substrate that increases the risk of conditions such as comorbidities and suicidality in BD patients.

      To investigate the moderating effect of gross family income on the association between demographic indicators and active commuting to work in Brazilian adults. Secondary analysis of the survey "Lifestyle and leisure habits of industry workers" (n=46,981), conducted in 24 Brazilian states (2006-2008). Self-reported information was collected with a previously tested questionnaire. Crude and adjusted logistic regression models were applied to analyze the association between sociodemographic variables (sex, age, marital status, number of children, education, country area and company size) and active commuting to work in different strata of gross family income. To test the moderating effect, an interaction analysis was applied. The proportion of active commuters among low-, medium- and high-income workers was 40.7% (95%CI:40.0%;41.5%), 27.0% (95%CI:26.3;27.6%) and 11.1%, (95%CI:10.5%;11.7%), respectively. The moderating effect of gross family income was confirmed. Men were more likely (OR:1.22 95%CI:1.12;1.32) to commute actively than women among low-income individuals. Active commuting was less likely among older workers in low-(OR30-39:0.90 95%CI: 0.83;0.98; OR≥40: 0.76 95%CI: 0.68;0.85) and medium-income strata (OR30-39:0.87 95%CI:0.80;0.95; OR≥40:0.84 95%CI:0.76;0.93) and among married individuals in high-income strata (OR:0.72 95%IC:0.61;0.84). Adults with lower education (ORhigh:10.80 95%CI:8.47;13.77), working in the south (ORhigh:1.93 95%CI:1.53;2.44) and in small companies (ORlow:2.50 95%CI:2.28;2.74) were more likely to commute actively; however, the magnitude of these associations differed at each income strata. There was an inverse association between gross family income and active commuting. Gross family income acts as a moderator of the association between demographic indicators and active commuting.

      ABSTRACT OBJECTIVE To describe the steps in the transcultural adaptation of the scale in the Effort-reward imbalance model to household and family work to the Brazilian context. METHODS We performed the translation, back-translation, and initial psychometric evaluation of the questionnaire that comprised three dimensions: (i) effort (eight items, emphasizing quantitative workload), (ii) reward (11 items that seek to capture the intrinsic value of family and household work, societal esteem, recognition from the spouse/partner, and affection from the children), and (iii) overcommitment (four items related to intrinsic effort). The scale was included in a sectional study conducted with 1,045 nursing workers. A subsample of 222 subjects answered the questionnaire for a second time, seven to 15 days thereafter. The data were collected between October 2012 and May 2013. The internal consistency of the scale was evaluated using Cronbach’s alpha and test-retest reliability analysis, square weighted kappa, prevalence and bias adjusted Kappa, and intraclass correlation coefficient. RESULTS Prevalence and bias-adjusted Kappa (ka) of the scale dimensions ranged from 0.80-0.83 for overcommitment, 0.78-0.90 for effort, and 0.76-0.93 for reward. In most dimensions, the values of minimum and maximum scores, average, standard deviation, and Cronbach’s alpha were similar in test and retest scores. Only on societal esteem subdimension (reward) was there little variation in standard deviation (test score of 2.24 and retest score of 3.36) and in Cronbach’s alpha coefficient (test score of 0.38 and retest score of 0.59). CONCLUSIONS The Brazilian version of the scale was found to have proper reliability indices regarding time stability, which suggests adapting it to be used in population with characteristics that are similar to the one in this study.

To identify among patients who had been previously defined as affected by T2DM those, in fact, affected by multigenerational diabetes; 2. After excluding patients carrying the most common MODY genes and mitochondrial mutations, we compared clinical features of remaining patients with those of patients with T2DM.Among 2,583 consecutive adult patients who had been defined as affected by T2DM, we looked for those with diabetes in ≥3 consecutive generations. All probands were screened for mutations in six MODY genes (HNF4A, GCK, HNF1A, PDX1, HNF1B and NeuroD1 and for the A3243G mitochondrial mutation. After excluding patients with mutations in one of such genes, we compared clinical features of the remaining 67 patients (2.6% of the whole initial sample affected by multigenerational "familial diabetes of the adulthood" (FDA and of their diabetic relatives (n = 63 to those with T2DM (n = 1,028 by generalized hierarchical linear models followed by pairwise comparisons.Age, age at diagnosis, proportion of hypertension (all p<0.001, and waist circumference (p<0.05 were lower in FDA than T2DM. Nonetheless, the two groups had similar age-adjusted incidence rate of all-cause mortality.Beside younger age at diagnosis, FDA patients show lower waist circumference and reduced proportion of hypertension as compared to those with T2DM; despite such reduced potential cardiovascular risk factors, FDA patients did not show a reduced mortality risk than patients with T2DM.

      Since 2009, legislation of the National School Feeding Program of Brazil (PNAE) institutionalizes its linkage with family farming as it establishes the requirement that at least 30% out of the total financial resources allocated by the federal government to the states and municipalities for school feeding must be used in the purchase of products directly from this sector. This study analyzes the process of drafting this legislation, focusing on the elements related to the procurement from family farming, through a historical contextualization, and it also presents a graphical representation with the main elements of this linkage: its objectives, target population, actions implemented and expected results. Actors involved with the drafting of the legislation were interviewed. The analyses show that the procurement from family farming is a far-reaching initiative in terms of the concept, execution and results. It has also showed that a strong articulation between the actors and institutions of the different sectors involved is critical to its success. The education, agriculture, planning, procurement and civil society sectors should work articulately at national, state and local level. The results of this study demonstrate that initiatives like this, of institutional procurement from family farming, which are currently being implemented in several countries, constitute as an important strategy of food and nutrition security, for the fulfillment of the human right to adequate food and the promotion of long-term sustainable development.

      The articles in this special issue show the vitality and progress of research on multigenerational aspects of social mobility, stratification, and inequality. The effects of the characteristics and behavior of grandparents and other kin on the statuses, resources, and positions of their descendants are best viewed in a demographic context. Intergenerational effects work through both the intergenerational associations of socioeconomic characteristics and also differential fertility and mortality. A combined socioeconomic and demographic framework informs a research agenda which addresses the following issues: how generational effects combine with variation in age, period, and cohort within each generation; distinguishing causal relationships across generations from statistical associations; how multigenerational effects vary across socioeconomic hierarchies, including the possibility of stronger effects at the extreme top and bottom; distinguishing between endowments and investments in intergenerational effects; multigenerational effects on associated demographic behaviors and outcomes (especially fertility and mortality); optimal tradeoffs among diverse types of data on multigenerational processes; and the variability across time and place in how kin, education, and other institutions affect stratification.

    16. Familial autoimmunity and polyautoimmunity in 60 Brazilian Midwest patients with systemic sclerosis

      Alex Magno Coelho Horimoto

      Full Text Available ABSTRACT Introduction: Systemic sclerosis (SSc is a connective tissue disease of unknown etiology, characterized by a triad of vascular injury, autoimmunity and tissue fibrosis. It is known that a positive family history is the greatest risk factor already identified for the development of SSc in a given individual. Preliminary observation of a high prevalence of polyautoimmunity and of familial autoimmunity in SSc patients support the idea that different autoimmune phenotypes may share common susceptibility variants. Objectives: To describe the frequency of familial autoimmunity and polyautoimmunity in 60 SSc patients in the Midwest region of Brazil, as well as to report the main autoimmune diseases observed in this association of comorbidities. Methods: A cross-sectional study with recruitment of 60 consecutive patients selected at the Rheumatology Department, University Hospital, Medicine School, Federal University of Mato Grosso do Sul (FMUFMS, as well as interviews of their relatives during the period from February 2013 to March 2014. Results: A frequency of 43.3% of polyautoimmunity and of 51.7% of familial autoimmunity in SSc patients was found. Patients with the presence of polyautoimmunity and familial autoimmunity presented primarily the diffuse form of SSc, but this indicator did not reach statistical significance. The autoimmune diseases most frequently observed in polyautoimmunity patients were: Hashimoto's thyroiditis (53.8%, Sjögren's syndrome (38.5%, and inflammatory myopathy (11.5%. The main autoimmune diseases observed in SSc patients' relatives were: Hashimoto's thyroiditis (32.3%, rheumatoid arthritis (22.6%, and SLE (22.6%. The presence of more than one autoimmune disease in SSc patients did not correlate with disease severity or activity. Conclusions: From the high prevalence of coexisting autoimmune diseases found in SSc patients, we stress the importance of the concept of shared autoimmunity, in order to promote a

The girl presented cleft palate and the boy showed cleft lip and palate as additional clinical signs. Both showed familial recurrence in fourth and third generations, respectively. The other family members also presented blepharophimosis, ptosis, and epicanthus inversus, but without lip and palatal involvement. There were no additional clinical signs nor infertility in these patients. To our knowledge this is the first instance of cleft lip and palate reported as additional signs of the BPES syndrome.Os autores descrevem uma menina e um menino com a síndrome de blefarofimose, ptose e epicanto inverso (BPES.

      This work reports the occurrence of mites predominantly predatory, phytophagous and with varied feeding habits on plants of the Atlantic Forest vegetation type of the State of Sao Paulo. The objective was to estimate the possible role of the Atlantic Forest vegetation as reservoir of these groups of mites which are also found on plants of agricultural importance. Samples were taken from 187 plant species belonging to 73 families in three vegetation types of the Atlantic Forest from February of 2001 to October of 2002. A total of 2,887 mites belonging to 163 morpho-species of 16 families were collected. Mite diversity was high, especially of predatory mites; these corresponded to 1,562 specimens of 92 morpho-species. Within this group, Phytoseiidae comprised 71% of the specimens and 62% of the morpho-species. Phytophagous mites comprised 836 specimens of 36 morpho-species. Within this group, Tenuipalpidae comprised the larger proportion of specimens (61%) whereas Tetranychidae corresponded to the larger proportion of morpho-species (64%). Mites with varied feeding habits corresponded to 491 specimens of 36 morpho-species. In this group, the larger proportion of specimens (52%) consisted of Ascidae and the larger proportion of morpho-species (42%) consisted of Tydeinae (family Tydeidae). High abundance and high morpho-species richness of mites of predominantly predatory, phytophagous and variable feeding habits were observed on 17, five and nine plant species, respectively. The results obtained suggest the importance of plants of the studied vegetation as reservoirs of predatory mites. (author)

      This work reports the occurrence of mites predominantly predatory, phytophagous and with varied feeding habits on plants of the Atlantic Forest vegetation type of the State of Sao Paulo. The objective was to estimate the possible role of the Atlantic Forest vegetation as reservoir of these groups of mites which are also found on plants of agricultural importance. Samples were taken from 187 plant species belonging to 73 families in three vegetation types of the Atlantic Forest from February of 2001 to October of 2002. A total of 2,887 mites belonging to 163 morpho-species of 16 families were collected. Mite diversity was high, especially of predatory mites; these corresponded to 1,562 specimens of 92 morpho-species. Within this group, Phytoseiidae comprised 71% of the specimens and 62% of the morpho-species. Phytophagous mites comprised 836 specimens of 36 morpho-species. Within this group, Tenuipalpidae comprised the larger proportion of specimens (61%) whereas Tetranychidae corresponded to the larger proportion of morpho-species (64%). Mites with varied feeding habits corresponded to 491 specimens of 36 morpho-species. In this group, the larger proportion of specimens (52%) consisted of Ascidae and the larger proportion of morpho-species (42%) consisted of Tydeinae (family Tydeidae). High abundance and high morpho-species richness of mites of predominantly predatory, phytophagous and variable feeding habits were observed on 17, five and nine plant species, respectively. The results obtained suggest the importance of plants of the studied vegetation as reservoirs of predatory mites. (author)

      Full Text Available Mercury pollution (MeHg up the aquatic food chains in the Amazonian ecosystems has been a major concern in environmental health. Riverside people (ribeirinhos along the Upper Madeira river are heavy fish eaters. Hair is the best biomarker for MeHg exposure. By assuming a constant hair growth rate, it is possible to evaluate a temporal profile of Hg exposure over the recent defined past. In this paper we present the segmental total hair Hg concentrations from a single family from which some of the 10 persons investigated had high hair Hg concentrations (peak of 339 ppm. We also presented the hair MeHg content from 4 out of the 10 family members investigated. There was a wide variation in total hair Hg concentrations (8 to 339 ppm among these individuals, who were mostly sharing their meals; there was also a wide variation in total Hg concentrations in the same individual over time (136 to 274 ppm. Hg speciation showed a mean and standard deviation in the MeHg content of 62% and 6%, respectively. The wide variation in total hair Hg concentration strongly indicated that it is possible to mitigate critical Hg exposure levels by conducting a fish advisory.

      BACKGROUND PRKAG2 syndrome diagnosis is already well-defined as Wolff-Parkinson-White syndrome (WPW), ventricular hypertrophy (VH) due to glycogen accumulation, and conduction system disease (CSD). Because of its rarity, there is a lack of literature focused on the treatment. The present study aimed to describe appropriate strategies for the treatment of affected family members with PRKAG2 syndrome with a long follow-up period. CASE REPORT We studied 60 selected individuals from 84 family members (32 males, 53.3%) (mean age 27±16 years). Patients with WPW and/or VH were placed in a group of 18 individuals, in which 11 (61.1%) had VH and WPW, 6 (33.3%) had isolated WPW, and 1 (5.6%) had isolated VH. Palpitations occurred in 16 patients (88.9%), chest pain in 11 (61.1%), dizziness in 13 (72.2%), syncope in 15 (83.3%), and dyspnea in 13 (72%). Sudden cardiac death (SCD) occurred in 2 (11.1%), and 2 patients with cardiac arrest (CA) had asystole and pre-excited atrial flutter-fibrillation (AFL and AF) as the documented mechanism. Transient ischemic attack (TIA) and learning/language disabilities with delayed development were observed. Genetic analysis identified a new missense pathogenic variant (p.K290I) in the PRKAG2 gene. Cardiac histopathology demonstrated the predominance of vacuoles containing glycogen derivative and fibrosis. The treatment was based on hypertension and diabetes mellitus (DM) control, antiarrhythmic drugs (AD), anticoagulation, and radiofrequency catheter ablation (RCA). Six patients (33.3%) underwent pacemaker implantation (PM). CONCLUSIONS The present study describes the clinical treatment for a rare cardiac syndrome caused by a PRKAG2 mutation.

      The fungus Batrachochytrium dendrobatidis (Bd) is among the main causes of declines in amphibian populations. This fungus is considered a generalist pathogen because it infects several species and spreads rapidly in the wild. To date, Bd has been detected in more than 100 anuran species in Brazil, mostly in the southern portion of the Atlantic forest. Here, we report survey data from some poorly explored regions; these data considerably extend current information on the distribution of Bd in the northern Atlantic forest region. In addition, we tested the hypothesis that Bd is a generalist pathogen in this biome. We also report the first positive record for Bd in an anuran caught in the wild in Amazonia. In total, we screened 90 individuals (from 27 species), of which 39 individuals (from 22 species) were Bd-positive. All samples collected in Bahia (2 individuals), Pernambuco (3 individuals), Pará (1 individual), and Minas Gerais (1 individual) showed positive results for Bd. We found a positive correlation between anuran richness per family and the number of infected species in the Atlantic forest, supporting previous observations that Bd lacks strong host specificity; of 38% of the anuran species in the Atlantic forest that were tested for Bd infection, 25% showed positive results. The results of our study exemplify the pandemic and widespread nature of Bd infection in amphibians.

      Full Text Available Income transfer programmes are common in various countries and play an important role in combating poverty. This article presents a review of the results of the Bolsa Família (Family Grant Programme, implemented in Brazil by the government of Lula da Silva in 2004. Over the last seven years many evaluations of the programme have been conducted, allowing an overview of its results and its strong and weak points to be mapped. Five central aspects relating to the programme are discussed in article five: (1 programme access, (2 hunger fighting results, (3 programme financial impacts, (4 conditioning factors of education and health, (5 supplementary programs and social mobility. The results of scientific research were presented for each of these aspects, and any of these believed to be convergent or divergent were discussed. As a general result it was concluded that the programme has generated significant results for the country, but there are still some issues that need to be reviewed, such as conditioning factors and the integrated management of the programme.

      Full Text Available Brazil has the largest public health-system in the world, with 120 million people covered by its free primary care services. The Family Health Strategy (FHS is the main primary care model, but there is no consensus on its impact on health outcomes. We systematically reviewed published evidence regarding the impact of the Brazilian FHS on selective primary care sensitive conditions (PCSC.We searched Medline, Web of Science and Lilacs in May 2016 using key words in Portuguese and English, without language restriction. We included studies if intervention was the FHS; comparison was either different levels of FHS coverage or other primary health care service models; outcomes were the selected PCSC; and results were adjusted for relevant sanitary and socioeconomic variables, including the national conditional cash transfer program (Bolsa Familia. Due to differences in methods and outcomes reported, pooling of results was not possible.Of 1831 records found, 31 met our inclusion criteria. Of these, 25 were ecological studies. Twenty-one employed longitudinal quasi-experimental methods, 27 compared different levels the FHS coverage, whilst four compared the FHS versus other models of primary care. Fourteen studies found an association between higher FHS coverage and lower post-neonatal and child mortality. When the effect of Bolsa Familia was accounted for, the effect of the FHS on child mortality was greater. In 13 studies about hospitalizations due to PCSC, no clear pattern of association was found. In four studies, there was no effect on child and elderly vaccination or low-birth weight. No included studies addressed breast-feeding, dengue, HIV/AIDS and other neglected infectious diseases.Among these ecological studies with limited quality evidence, increasing coverage by the FHS was consistently associated with improvements in child mortality. Scarce evidence on other health outcomes, hospitalization and synergies with cash transfer was found.

      Full Text Available Inherited disorders of hemoglobin, the most common monogenic disease, are now well understood at the molecular level, knowledge, which has led to considerable improvements in their control and management. The Brazilian population is multiethnic, and the correct characterization of the Hb D is important, mainly because the method available for detection of abnormal hemoglobins, present a migration in the same zone at alkaline pH, for Hb S, D, and G for example. In this paper we studied a family with an abnormal hemoglobin like S in alkaline electrophoresis, by appropriated methods including HPLC and molecular analysis, characterized as hemoglobin D Los Angeles.As doenças hereditária da hemoglobina são as mais comuns doenças monogênicas e atualmente bem conhecidas do ponto de vista molecular, fato este que propiciou um avanço no seu controle e manuseio. A população brasileira caracteriza-se pela multiplicidade étnica e a caracterização da Hb D torna-se importante por este dado, associado ao fato de que os métodos de detecção das hemoglobinopatias comumente não identificam esta fração anormal que apresenta a peculiaridade de migração eletroforéticia em pH alcalino na mesma zona observada nas Hb S e G. Neste relato é apresentado um estudo familiar no qual é empregada metodologia adequada, o HLPC, que permite a identificação da Hb D.

      A multigeneration test is used to show disruption of the reproductive system by phytosterols. - Zebrafish from mixed sex populations were exposed continuously across three generations to two phytosterol preparations both containing β-sitosterol. The phytosterols were isolated from wood and soy beans. Blood vitellogenin levels and sex ratio changes were used as intermediate indicators of the reproduction failures. Both sterol preparations caused vitellogenin induction in the exposed fish. The wood sterol changed the sex ratio of the exposed fish. In generation F1, the predominant sex was male, and in generation F2 it was female. The soy sterol in the used test concentration was lethal to the exposed fish in generation F1. This multigeneration test evidenced that phytosterols containing β-sitosterol disrupt the reproduction system of zebrafish by changing the sex ratios and by inducing the vitellogenin production in the exposed fish

      2015-01-01

      Full Text Available The urgency of this research arises from the convergence of two dynamics that are transforming the workplace and impacting organization performance. The first is multigenerational workforce work side by side in the same organization even in the same team. The second is informal learning, a major mode of learning in an organization. Therefore, this paper aims to explore the influence of generational background of Baby Boomers, Generation X and Generation Y in relation to informal team learning in the Indonesian business environment. Both, qualitative and quantitative studies were conducted with 21 interviewees and 184 survey respondents representing a total of 191 multigenerational teams participating in this research. The findings suggest that generational background influence informal learner and effective informal team learning, but have no direct impact on team climate. Understanding generational differences will enable individuals to learn informally and create a conducive team climate that will lead to effective informal team learning.

      What happens when you find yourself working in your medical practice every day with co-workers who are the ages of your parents or children? Do you find yourself reverting to age-related roles? Do you become exasperated with or bewildered by the values and behaviors of older or younger colleagues? This article explores the challenges and opportunities the medical practice staff member faces when he or she is part of a multi-generational medical practice team. It describes the tensions that often occur when a medical practice staff runs the gamut from those who remember using a library card catalog and those who can't remember the days before Google. It describes the core values, career goals, key formative events, and attitudes that may have shaped the thinking and behavior of the four generations that may work in the medical practice today: Traditionalists, Baby Boomers, Generation X, and Generation Y. It suggests preferred communication and learning methods for staff members of different generations. Finally, this article offers 10 best practices for working in a multi-generational staff and for creating a supportive multi-generational medical practice culture.

Sugerimos que já nas narrativas ensaísticas sobre a identidade nacional existem modelos plurais de família brasileira, diversificados em termos da compreensão dos arranjos locais de relações familiares. Com esse objetivo, relemos, sob o eixo família-nação-região, dois conjuntos de ensaístas significativos para a construção de identidades regionais particulares (primeiro, Alfredo Ellis Jr. e Cassiano Ricardo; segundo, Alceu Amoroso Lima e Sylvio de Vasconcellos, pensadores/produtores de visões de São Paulo e de Minas Gerais, respectivamente, enquanto culturas e sociedades em grande parte caracterizadas por suas experiências de organização familiar própria.Revisions of classical studies of the family in Brazil agree in criticizing patriarchalism as a general and fixed model describing this institution, arguing that the Brazilian family was a plurality of dispersed experiences. We suggest that in the essay narratives of national identity there are already plural models of the Brazilian family, which are diversified according to local arrangements of family relations. Considering the themes family-nation-region, we review the work of two groups of important essayists on the construction of particular regional identities: Alfredo Ellis Jr. e Cassiano Ricardo; Alceu Amoroso Lima e Sylvio de Vasconcellos. We argue that these essayists articulated visions of São Paulo and Minas Gerais as cultures and societies characterized in a significant way by experiences of a proper family organization.

      To describe the steps in the transcultural adaptation of the scale in the Effort-reward imbalance model to household and family work to the Brazilian context. We performed the translation, back-translation, and initial psychometric evaluation of the questionnaire that comprised three dimensions: (i) effort (eight items, emphasizing quantitative workload), (ii) reward (11 items that seek to capture the intrinsic value of family and household work, societal esteem, recognition from the spouse/partner, and affection from the children), and (iii) overcommitment (four items related to intrinsic effort). The scale was included in a sectional study conducted with 1,045 nursing workers. A subsample of 222 subjects answered the questionnaire for a second time, seven to 15 days thereafter. The data were collected between October 2012 and May 2013. The internal consistency of the scale was evaluated using Cronbach's alpha and test-retest reliability analysis, square weighted kappa, prevalence and bias adjusted Kappa, and intraclass correlation coefficient. Prevalence and bias-adjusted Kappa (ka) of the scale dimensions ranged from 0.80-0.83 for overcommitment, 0.78-0.90 for effort, and 0.76-0.93 for reward. In most dimensions, the values of minimum and maximum scores, average, standard deviation, and Cronbach's alpha were similar in test and retest scores. Only on societal esteem subdimension (reward) was there little variation in standard deviation (test score of 2.24 and retest score of 3.36) and in Cronbach's alpha coefficient (test score of 0.38 and retest score of 0.59). The Brazilian version of the scale was found to have proper reliability indices regarding time stability, which suggests adapting it to be used in population with characteristics that are similar to the one in this study.

      This paper aims to characterize the Brazilian population who spent money with tobacco products. POF dataset was used from IBGE of the years 2008 and 2009. The same definition that IBGE usually use for tobacco consumer was applied, which is someone has spent money with any kind of tobacco products and its derivatives. It was used individual aspects taking into account such as gender, schooling, age (over 14 years old), income lines, regions and ethnics to characterize these populations. Descriptive statistics were employed to estimate the results and the complex sample design of the survey was considered. According to our results, on average, 10% of the Brazilian population have spent money with tobacco products. Besides, these people are older, earn low salaries and have less schooling than someone who does not consume tobacco. Moreover, for this population 1.5% of the family budget is spent on tobacco products. Last but not least, the most of tobacco consumers are men. In general, money which is spent on tobacco products can cause impressive effects on domestic budget because this value could supply other important necessities to the family. Although there are many monitoring and prevention strategies to avoid tobacco consume, deep knowledge about this population that actually consume these products can increase the efficacy of more specific policies.

      Full Text Available RESUMONo âmbito da empresa familiar, conciliar os objetivos organizacionais e as expectativas da família empresária multigeracional não constitui tarefa simples. Este trabalho foi realizado com o objetivo de analisar os mecanismos de governança e os processos de sucessão e de profissionalização implementados em uma empresa familiar brasileira longeva de grande porte. Além disso, visou identificar prováveis níveis de inter-relação entre esses processos e avaliar suas possibilidades como mediadores das relações de propriedade e controle em uma empresa familiar. Foi realizada uma pesquisa qualitativa, por meio de estudo de caso, junto ao grupo Randon S/A, que iniciou um longo processo de reestruturação nos anos 1990, ainda não concluído. Os resultados da pesquisa indicam que fatores endógenos e exógenos, como os processos de crescimento e internacionalização da empresa, a reformulação da estrutura patrimonial, o ingresso de novos sócios e a entrada no Nível 1 de governança corporativa da Bovespa, dentre outros, influenciaram as mudanças que ocorreram na estrutura de propriedade, de poder, de controle e de gestão da organização. Decisões estratégicas da família controladora incluíram profissionalizar a gestão das empresas que compõem a holding, adotar estruturas de governança que possibilitam demarcar a propriedade e a gestão e reduzir conflitos de interesses, bem como definir regras claras para a sucessão. Esses elementos foram corroborados por essa pesquisa como importantes componentes do processo de construção de longevidade da empresa familiar.ABSTRACTIn the context of a family business, harmonizing organizational objectives and the expectations of a multi-generational business-owning family is no easy task.

      Full Text Available Over the next few years, the efficient use of next-generation sequencing (NGS in human genetics research will depend heavily upon the effective mechanisms for the selective enrichment of genomic regions of interest. Recently, comprehensive exome capture arrays have become available for targeting approximately 33 Mb or approximately 180,000 coding exons across the human genome. Selective genomic enrichment of the human exome offers an attractive option for new experimental designs aiming to quickly identify potential disease-associated genetic variants, especially in family-based studies. We have evaluated a 2.1 M feature human exome capture array on eight individuals from a three-generation family pedigree. We were able to cover up to 98% of the targeted bases at a long-read sequence read depth of > or = 3, 86% at a read depth of > or = 10, and over 50% of all targets were covered with > or = 20 reads. We identified up to 14,284 SNPs and small indels per individual exome, with up to 1,679 of these representing putative novel polymorphisms. Applying the conservative genotype calling approach HCDiff, the average rate of detection of a variant allele based on Illumina 1 M BeadChips genotypes was 95.2% at > or = 10x sequence. Further, we propose an advantageous genotype calling strategy for low covered targets that empirically determines cut-off thresholds at a given coverage depth based on existing genotype data. Application of this method was able to detect >99% of SNPs covered > or = 8x. Our results offer guidance for "real-world" applications in human genetics and provide further evidence that microarray-based exome capture is an efficient and reliable method to enrich for chromosomal regions of interest in next-generation sequencing experiments.

      A Cd exposure (3 μg L -1 ) experiment was conducted for six successive generations to investigate the responses to chronic Cd stress in Daphnia magna. We observed a biphasic accumulation of Cd in the six generations and suggested a similar pattern with respect to daphnids' tolerance. Cd assimilation efficiencies, daphnid growth, and reproduction corresponded to the changes of tolerance, which was partially accounted for by metallothionein induction. When maternally exposed neonates grew in Cd-free water for one or two generations, their growth, MT concentration and biokinetic parameters partially or totally recovered. The rapid recovery suggests the high potential for ecological restoration from Cd pollution. Our results indicate that the tolerance of sensitive D. magna clones to Cd was dependent on long-term or multigenerational exposure. The tolerance developed within the first several generations might not be maintained, and the animals may become even more sensitive to Cd stress in subsequent generations. - Tolerance of sensitive Daphnia magna clones to cadmium was dependent on long-term or multigenerational exposure

      Despite burgeoning evidence linking early exposure to child maltreatment (CM) to deficits in self-regulation, the pathways to strong regulatory development in these children are not well understood, and significant heterogeneity is observed in their outcomes. Experiences of autonomy may play a key role in transmitting self-regulatory capacity across generations and help explain individual differences in maltreatment outcomes. In this study, we investigated multigenerational associations between Generation 1 (G1)-Generation 2 (G2) mothers' early experience of warmth and autonomy in relation to their own mothers and their Generation 3 (G3) children's autonomic physiological regulation in CM (n = 85) and non-CM (n = 128) families. We found that G2 mothers who recalled greater autonomy in their childhood relationship with their G1 mothers had preschool-age G3 children with higher respiratory sinus arrhythmia at baseline when alone while engaged in individual challenge tasks, during social exchanges with their mother in joint challenge tasks, and during the portions of the strange situation procedure when the mother was present. Although no clear mediators of this association emerged, multigenerational links among G1-G2 relations, maternal representations of her child, child behavior, and child respiratory sinus arrhythmia differed by maltreatment status, thus possibly representing important targets for future research and intervention.

      The purpose of the present study is to determine the cultural and social barriers that are preventing Laredoans from accessing the digital world. This multigenerational study examines how three generations within 16 families relate culturally and socially to technology. Three members from the same family were invited to voluntarily participate in the study, with a total of 48 in-depth, face-to-face interviews being conducted. The present study identified several barriers such as low educational level, low income, lack of English language proficiency, lack of relevant content available in other languages besides English, preference to communicate face-to-face, fear of violence, and endless working hours. Laredo is the least connected city in the nation with 40.2% non-connectivity rate. Research is needed to understand this digital inequity situation in this borderland city. The theoretical framework used is rooted on Straubhaar’s concepts of techno-field, techno-disposition, and techno-capital.

      Full Text Available Structural changes imposed on Brazil’s dairy industry are influenced by the international market while it presses local industries and local producers. One of the main difficulties in the dairy sector is the standardization of milk based on the international standards of quality. So, to meet these requirements, standard operating procedures are established for the entire production chain, and they’re called '' Good dairy farming practices”. This paper addresses in a systemic way the influences of these standards in the Brazilian milk production, and the difficulties for adopting these procedure standards in family farming, especially in the Amazon region. The Amazonian family farmer is characterized by a peculiar diversity related to the ways they produce and live in society. In addition, there is at the same time a variety of local contexts very striking in the Amazon, which involve and influence the practices of farmers, making it difficult to join a homogenizing principle of good practices. The criticism of this paper does not report the need for sanitation improvements in milk production practices, but it wants to demonstrate as a leading line that the local context and the logic of producers are extremely necessary, so that the actions elaborated can value their practices and have them as a starting point. It should be noted in this study that the result of standard procedures for family farmers is the differentiation and social reunification in between them, where some are consolidated in milk production and others are excluded.

    1. Multigeneric Intertextuality in Advertising: Discourse Strategy from a Cognitive Perspective

      Full Text Available Advert recipients have wide-ranging experiences of perceiving other texts. When these experiences become the basis of perceiving advert messages, we speak of intertextuality operating as a discourse strategy. This paper studies multigeneric intertextuality in printed advertising, i.e. delivering an advert message through a register or text-form typical of other genres, for which discourse analysis and the genre studies perspective are adapted. From the cognitive linguistics perspective, it focuses on how the experience becomes the basis of building an emotive and attitudinal layer of meaning via exploring the recipient's mental space. The article studies cues signalling intertextual processing, specifically cues of socially determined discourses such as cooking recipes, warning signs, computer-mediated communication, scientific discussions or travel brochures, which may function as mental space inducing cues in the collected adverts. It also deals with how intertextuality in adverts can be scaled and how the level of explicitness relates to promoting various categories of products.

      OBJECTIVES: Using longitudinal data from the multigenerational Youth Development Study (YDS), this article documents how parents’ long-term smoking trajectories are associated with adolescent children’s likelihood of smoking. Prospective data from the parents (from age 14–38 years) enable unique comparisons of the parents’ and children’s smoking behavior, as well as that of siblings. METHODS: Smoking trajectories are constructed using latent class analysis for the original YDS cohort (n = 1010). Multigenerational longitudinal data from 214 parents and 314 offspring ages 11 years and older are then analyzed by using logistic regression with cluster-corrected SEs. RESULTS: Four latent smoking trajectories emerged among the original cohort: stable nonsmokers (54%), early-onset light smokers who quit/reduce (16%), late-onset persistent smokers (14%), and early-onset persistent heavy smokers (16%). Although 8% of children of stable nonsmokers smoked in the last year, the other groups’ children had much higher percentages, ranging from 23% to 29%. Multivariate logistic regression models confirm that these significant differences were robust to the inclusion of myriad child- and parent-level measures (for which child age and grade point average [GPA] are significant predictors). Older sibling smoking, however, mediated the link between parental heavy smoking and child smoking. CONCLUSIONS: Even in an era of declining rates of teenage cigarette use in the United States, children of current and former smokers face an elevated risk of smoking. Prevention efforts to weaken intergenerational associations should consider parents’ long-term cigarette use, as well as the smoking behavior of older siblings in the household. PMID:23918887

      To validate the Brazilian Portuguese version of the Family Environment Assessment questionnaire (Inventaire du Milieu Familial). The validation process was carried out in two stages. First, translation and back-translation were performed, and in the second phase, the questionnaire was applied in 72 families of children between 0 and 24 months for the validation process. The tool consists of the following domains: mother's communication ability; behavior; organization of the physical and temporal environment; collection/quantity of toys; maternal attitude of constant attention toward her baby; diversification of stimuli; baby's behavior. The following was performed for the scale validation: 1 - content analysis (judgment); 2 - construct analysis (factorial analysis - Kaiser-Meyer-Olkin, Bartlett, and Pearson's correlation tests); 3 - criterion analysis (calculation of Cronbach's alpha coefficient, intraclass correlations, and split-half correlations). The mean age of the children was 9±6.7 months, and of these, 35 (48.6%) were males. Most correlations between items and domains were significant. In the factorial analysis of the scale, Kaiser-Meyer-Olkin values were 0.76, Bartlett's test showed a p-value<0.001, and correlation between items and domains showed a p-value<0.01. Regarding the validity, Cronbach's alpha was 0.92 (95% CI: 0.89-0.94). The intraclass correlation among the evaluators was 0.97 (0.96-0.98) and split-half correlations, r: 0.60, with p<0.01. The Portuguese version of the Inventaire du Milieu Familial showed good to excellent performance regarding the assessed psychometric properties. Copyright © 2018. Published by Elsevier Editora Ltda.

      2012-01-01

      Background Childhood depression affects the morbidity, mortality and life functions of children. Individual, family and environmental factors have been documented as psychosocial risk factors for childhood depression, especially family violence, which results in inadequate support, low family cohesion and poor communication. This study investigates the association between psychosocial depression factors in low-income schoolchildren and reveals the potential trouble spots, highlighting several forms of violence that take place within the family context. Methods The study was based on a cross-sectional analysis of 464 schoolchildren aged between 6 and 10, selected by random sampling from a city in the state of Rio de Janeiro, Brazil. Socio-economic, family and individual variables were investigated on the strength of the caregivers’ information and organized in blocks for analysis. A binary logistic regression model was applied, according to hierarchical blocks. Results The final hierarchical regression analysis showed that the following variables are potential psychosocial factors associated with depression in childhood: average/poor relationship with the father (OR 3.24, 95% CI 1.32-7.94), high frequency of victimization by psychological violence (humiliation) (OR 6.13, 95% CI 2.06-18.31), parental divorce (OR 2.89, 95% CI 1.14-7.32) and externalizing behavior problems (OR 3.53 IC 1.51-8.23). Conclusions The results point to multiple determinants of depressive behavior in children, as well as the potential contribution of psychological family violence. The study also reveals potential key targets for early intervention, especially for children from highly vulnerable families. PMID:22776354

      Clévia Rosset

      Full Text Available Tuberous sclerosis complex (TSC is an autosomal dominant multisystem disorder characterized by the development of multiple hamartomas in many organs and tissues. It occurs due to inactivating mutations in either of the two genes, TSC1 and TSC2, following a second hit in a tumor suppressor gene in most hamartomas. Comprehensive screening for mutations in both the TSC1 and TSC2 loci has been performed in several cohorts of patients and a broad spectrum of pathogenic mutations have been described. In Brazil, there is no data regarding incidence and prevalence of tuberous sclerosis and mutations in TSC1 and TSC2. We analyzed both genes in 53 patients with high suspicion of tuberous sclerosis using multiplex-ligation dependent probe amplification and a customized next generation sequencing panel. Confirmation of all variants was done by the Sanger method. We identified 50 distinct variants in 47 (89% of the patients. Five were large rearrangements and 45 were point mutations. The symptoms presented by our series of patients were not different between male and female individuals, except for the more common occurrence of shagreen patch in women (p = 0.028. In our series, consistent with other studies, TSC2 mutations were associated with a more severe phenotypic spectrum than TSC1 mutations. This is the first study that sought to characterize the molecular spectrum of Brazilian individuals with tuberous sclerosis.

      Full Text Available The aim of this study was to determine whether random amplified polymorphic DNA (AP-PCR analysis is able to differentiate genetically different clones of mutans streptococci, in 22 Brazilian family members. Stimulated saliva samples were collected from fathers, mothers and infants. For 5-18 months babies with erupting primary dentition, plaque samples were collected using sterile tooth pick tips. From these samples, mutans streptococci were isolated on SB-20 agar plates. After growth, representative colonies were identified by biochemical methods on the basis of carbohydrate fermentation. Streptococcus mutans isolates were obtained from all family members and AP-PCR typed separately with a random primer (OPA-13. Bacterial cell lysates were used as template in PCR reactions and the amplified DNA fragments obtained were compared by agarose gel electrophoresis. Results demonstrated that the father shared the baby's genotype in three families and the mother shared the baby's genotype in 12 families seven babies harbored Streptococcus mutans strains similar to those of their siblings. The technique was able to demonstrate the genetic Streptococcus mutans in Brazilian family members.O objetivo deste estudo foi determinar, através da técnica de reação em cadeia da polimerase com primers arbitrários (AP-PCR a capacidade de diferenciar clones geneticamente distintos de Streptococcus mutans e estabelecer o grau de similaridade intrafamilial para os isolados.

      Thermodynamic analysis of a renewable-based multi-generation energy production system which produces a number of outputs, such as power, heating, cooling, hot water, hydrogen and oxygen is conducted. This solar-based multi-generation system consists of four main sub-systems: Rankine cycle, organic Rankine cycle, absorption cooling and heating, and hydrogen production and utilization. Exergy destruction ratios and rates, power or heat transfer rates, energy and exergy efficiencies of the system components are carried out. Some parametric studies are performed in order to examine the effects of varying operating conditions (e.g., reference temperature, direct solar radiation and receiver temperature) on the exergy efficiencies of the sub-systems as well as the whole system. The solar-based multi-generation system which has an exergy efficiency of 57.35%, is obtained to be higher than using these sub-systems separately. The evaluation of the exergy efficiency and exergy destruction for the sub-systems and the overall system show that the parabolic dish collectors have the highest exergy destruction rate among constituent parts of the solar-based multi-generation system, due to high temperature difference between the working fluid and collector receivers. -- Highlights: ► Development of a new multi-generation system for solar-based hydrogen production. ► Investigation of exergy efficiencies and destructions in each process of the system. ► Evaluation of varying operating conditions on the exergy destruction and efficiency

      Over the past several years, leaders in healthcare have noticed an increase in generational tension among employees, most often focused on the attitudes and behaviors of the arriving millennials (generation Y). While these employee relations issues were a nuisance, they rarely rose to the level of a priority demanding leadership intervention. Some leaders, in fact, hoped that the issues would resolve themselves as these young employees settled in and learned that they had to demonstrate new behaviors to be successful in the workplace. Most organizations adopted this wait-and-see attitude. Not so today. As the boomer generation has begun its exodus from the workplace, organizations are increasingly looking at the millennials as not a problem but a solution to the workplace manpower transition that is under way. Our problem is that we don't yet know how best to lead such a diverse, multigenerational workforce. This article examines the generational topic and provides advice concerning a variety of changes that leaders may implement to advance their organization's ability to attract and to retain the millennials.

A compreensão de tais lógicas distintas requer que investiguemos os diferentes signficados do patimônio territorial em cada contexto social e cultural. Embora a herança seja baseada na noção de consanguinidade, as regras costumeiras não reconhecem os mesmos direitos para todos os filhos.

      Multigeneration feeding studies have been carried out to investigate the effects of long-term feeding of an irradiated whole diet in Wistar rats. The parent and the four successive generations were fed on a nutritionally adequate test diet exposed to either 0.2 or 2.5Mrad gamma radiation and the effects, if any, on various parameters of animal health were assessed. In addition to an unirradiated test control, a historical control group fed on stock laboratory rations was also employed for comparison. The test diet consisted of various components including some of the basic ingredients of human diet in India. Exposure of the test diet to 0.2 or 2.5Mrad did not affect the food efficiency ratio and there were no significant differences in the growth rates of animals fed on unirradiated or irradiated diets. Reproductive performance of the rats fed on irradiated or unirradiated diets belonging to the parent, first, second or third generations were also comparable. Mortality rates and reproductive function in relation to age were also not altered due to feeding of irradiated whole diets. The haematological profile and the serum enzymes of the animals of all the generations fed irradiated diets were within normal limits. Though some differences were observed in the relative weights of some organs, these effects were limited to a particular generation, did not show any definite pattern and could not be related to the ingestion of irradiated diets. First-generation rats examined at 100-104 weeks for gross pathological manifestations including tumour incidence also did not indicate any significant differences among groups. (author)

    17. Brazilian women in politics.

      Women are gradually gaining influence in Brazilian politics, especially since recent advances in the women's movement, but they still play a limited role. There have been journals devoted to feminism and some notable feminists since 1850. In 1932 suffragettes in Brazil gained women the right to vote. Women's associations burgeoned in the 1940s and 1950s, culminating in a peak in number of women in national elected positions in 1965. A repressive military regime reversed the process, which resumed in 1975. 1975 was also significant for the Brazilian women's movement because of the U.N. Women's Year. Several large, influential feminist political action groups were formed, typically by upper class women with leftist views, although some church and union groups from lower classes also appeared. In 1979-1981, the coherence of these groups fell into schism and fragmentation, because of disagreements over the feminist political doctrines and roles, views on legality of abortion, and special interest groups such as lesbians. Another bitter dispute is opposition by leftist women to BEMFAM, the Brazilian Society of Family Welfare, which provides family planning for the poor: leftists oppose BEMFAM because it is supported by funds from "imperialist" countries such as the U.S. There are several types of feminists groups: those that emphasize health, sexuality and violence; those composed of lesbians; those originating from lower classes and unions; publicly instituted organizations. Brazilian law forbids discrimination against women holding public office, but in reality very few women actually do hold office, except for mayors of small towns and a few administrators of the Education and Social Security ministries. Political office in Brazil is gained by clientism, and since women rarely hold powerful positions in business, they are outsiders of the system. Brazilian women have achieved much, considering the low female literacy rate and traditional power system, but their

      This study aimed to assess the impact of parent reported sleep bruxism, trait anxiety and sociodemographic/socioeconomic features on quality of life related to oral health (OHRQoL) of children and their families. Healthy children aged 3-7 years, with (n=34) and without (n=32) bruxism were select for this study. Data was collected by applying the following instruments: The Early Childhood Oral Health Scale (B-ECOHIS) and Trait-anxiety Scale (TAS). The sociodemographic/socioeconomic characteristics were obtained by interviews with parents. Multiple logistic regression tests were performed to observe the influence of sociodemographic/socioeconomic characteristics, bruxism and trait-anxiety on the children's OHRQoL. No association between sleep bruxism and all evaluated sociodemographic/socioeconomic conditions, with exception of being the only child (p=0.029), were observed. Mean B-ECOHIS and TAS scores were different (pbruxism. Although an association between bruxism and OHRQoL (p=0.015) was observed, it was dropped (p=0.336; OR=1.77) in the logistic regression model. Trait anxiety was the variable responsible for the impact on the OHRQoL of children (p=0.012; OR=1.05). Our results indicated anxiety as the main factor that interfered in the OHRQoL of children with sleep bruxism.

      The purpose of this preliminary observational study was to evaluate the usefulness of a humanitarian initiative, aimed at improving the neuropsychological and behavioral attitude of children with severe socioeconomic and cultural hardship, in the Brazilian state of Pará. This humanitarian initiative was realized through the administration of two neuromodulation protocols, with radioelectric asymmetric conveyor (REAC) technology. During several years of clinical use, the REAC neuromodulation protocols have already proved to be effective in countering the effects of environmental stress on neuropsycho-physical functions. After the preliminary medical examination, all subjects were investigated with the Strengths and Difficulties Questionnaire (SDQ), including the impact supplement with teacher's report. After the SDQ, they received the neuromodulation treatment with REAC technology named neuro postural optimization (NPO), to evaluate their responsiveness. Subsequently, every 3 months all subjects underwent a treatment cycle of neuropsycho-physical optimization (NPPO) with REAC technology, for a total of three cycles. At the end of the last REAC-NPPO treatment cycle, all subjects were investigated once again with the SDQ. For the adequacy of the data, the Wilcoxon and the Signs tests were used. For the subdivision into clusters, the Kruskal-Wallis test was applied for the adequacy of the procedure. For all the applied tests, a statistical significance of p <0.5 was found. The results showed that the REAC-NPO and REAC-NPPO neuromodulation protocols are able to improve the quality of life, the scholastic and socialization skills, and the overall state of physical and mental health in children of a family with severe socioeconomic and cultural hardship. The REAC-NPO and REAC-NPPO neuromodulation protocols, due to their non-invasive characteristics, painlessness, and speed of administration, can be hypothesized as a treatment to improve the overall state of physical and

The frequency of allele 2 of the (GTn polymorphism was higher in leprosy patients [p = 0.04, odds ratio (OR = 1.49], whereas the frequency of allele 3 was higher in the control group (p = 0.03; OR = 0.66. Patients carrying the 274T allele (p = 0.04; OR = 1.49 and TT homozygosis (p = 0.02; OR = 2.46, such as the 469+14C allele (p = 0.03; OR = 1.53 of the 274C/T and 469+14G/C polymorphisms, respectively, were more frequent in the leprosy group. The leprosy and control groups had similar frequency of the 577-18G/A, 823C/T, 1029C/T, 1465-85G/A, 1703G/A, and 1729+55del4 polymorphisms. The 274C/T polymorphism in exon 3 and the 469+14G/C polymorphism in intron 4 were associated with susceptibility to leprosy, while the allele 2 and 3 of the (GTn polymorphism in the promoter region were associated with susceptibility and protection to leprosy, respectively.

      This study examined gender differences in the association between work-family conflict and self-rated health and evaluated the effect of educational attainment. We used baseline data from ELSA-Brasil, a cohort study of civil servants from six Brazilian state capitals. Our samples included 12,017 active workers aged 34-72 years. Work-family conflict was measured by four indicators measuring effects of work on family, effects of family in work and lack of time for leisure and personal care. Women experienced more frequent work-family conflict, but in both genders, increased work-family conflict directly correlated with poorer self-rated health. Women's educational level interacted with three work-family conflict indicators. For time-based effects of work on family, highly educated women had higher odds of suboptimal self-rated health (OR = 1.54; 95 % CI = 1.19-1.99) than less educated women (OR = 1.14; 95 % CI = 0.92-1.42). For strain-based effects of work on family, women with higher and lower education levels had OR = 1.91 (95 % CI 1.48-2.47) and OR = 1.40 (95 % CI 1.12-1.75), respectively. For lack of time for leisure and personal care, women with higher and lower education levels had OR = 2.60 (95 % CI = 1.95-3.47) and OR = 1.11 (95 % CI = 0.90-1.38), respectively. Women's education level affects the relationship between work-family conflict and self-rated health. The results may contribute to prevention activities.

    9. II Spatial metaphors and somatic communication: the embodiment of multigenerational experiences of helplessness and futility in an obese patient.

      Science.gov (United States)

      2013-06-01

      This paper explores the analysis of an obese woman who came to experience her flesh as a bodying forth of personal and multigenerational family and cultural experiences of helplessness. The paper discusses the ideas and images that formed the basis of how I engaged with these themes as they presented countertransferentially. My thesis is that clinical approaches which draw on spatial metaphors for the psyche offer valuable tools for working with people whose inner world expresses itself somatically because such metaphors can be used to engage simultaneously with the personal, cultural, and ancestral dimensions of these unconscious communications. The paper builds on Jung's view of the psyche as comprised of pockets of inner otherness (complexes), on Redfearn's image of psyche as landscape-like and on Samuels' thinking on embodied countertransference and on the political psyche. It also draws on Butler's work on the body as a social phenomenon and on the theme of being a helpless non-person or nobody as explored in Tom Stoppard's play Rosencrantz and Guildenstern are Dead which retells Shakespeare's Hamlet from the perspective of two of the play's 'bit' characters. © 2013, The Society of Analytical Psychology.

      Full Text Available The Bolsa Escola (‘school stipend’ and its successor the Bolsa Familia (‘family stipend’ schemes have formed a crucial and successful part of Brazil’s welfare program. Bolsa Escola provided aid to Brazil’s poorest families on the condition that their children attended school, and Bolsa Familia has extended this idea, giving aid on the condition that children both attend school and receive vaccinations. Bolsa Familia is currently the largest Conditional Cash Transfer Program (CCTP in the world, costing roughly 0.5% of Brazilian GDP and helping around 11.2 million families (around 44 million Brazilians, constituting roughly one fifth of the population. Multilateral institutions have praised the schemes, and they are setting a leading example to other developing nations. In 2005, Paul Wolfowitz (former president of the World Bank said, ‘Bolsa Familia has already become a highly praised model of effective social policy. Countries around the world are drawing lessons from Brazil’s experience and are trying to produce the same results for their own people’.

      Natal philopatry, the return of individuals to their natal area for reproduction, has advantages and disadvantages for animal populations. Natal philopatry may generate local genetic adaptation, but it may also increase the probability of inbreeding that can compromise persistence. Although natal philopatry is well documented in anadromous fishes, marine fish may also return to their birth site to spawn. How philopatry shapes wild fish populations is, however, unclear because it requires constructing multigenerational pedigrees that are currently lacking for marine fishes. Here we present the first multigenerational pedigree for a marine fish population by repeatedly genotyping all individuals in a population of the orange clownfish (Amphiprion percula) at Kimbe Island (Papua New Guinea) during a 10-y period. Based on 2927 individuals, our pedigree analysis revealed that longitudinal philopatry was recurrent over five generations. Progeny tended to settle close to their parents, with related individuals often sharing the same colony. However, successful inbreeding was rare, and genetic diversity remained high, suggesting occasional inbreeding does not impair local population persistence. Local reproductive success was dependent on the habitat larvae settled into, rather than the habitat they came from. Our study suggests that longitudinal philopatry can influence both population replenishment and local adaptation of marine fishes. Resolving multigenerational pedigrees during a relatively short period, as we present here, provides a framework for assessing the ability of marine populations to persist and adapt to accelerating climate change.

      Generally, ecotoxicologists rely on short-term tests that assume populations to be static. Conversely, natural populations may be exposed to the same stressors for many generations, which can alter tolerance to the same (or other) stressors. The objective of this study was to improve our understanding of how multigenerational stressors alter life history traits and stressor tolerance. After continuously exposing Daphnia magna to cadmium for 120 days, we assessed life history traits and conducted a challenge at higher temperature and cadmium concentrations. Predictably, individuals exposed to cadmium showed an overall decrease in reproductive output compared to controls. Interestingly, control D. magna were the most cadmium tolerant to novel cadmium, followed by those exposed to high cadmium. Our data suggest that long-term exposure to cadmium alter tolerance traits in a non-monotonic way. Because we observed effects after one-generation removal from cadmium, transgenerational effects may be possible as a result of multigenerational exposure. - Highlights: • Daphnia magna exposed to cadmium for 120 days. • D. magna exposed to cadmium had decreased reproductive output. • Control D. magna were most cadmium tolerant to novel cadmium stress. • Long-term exposure to cadmium alter tolerance traits in a non-monotonic way. • Transgenerational effects observed as a result of multigenerational exposure. - Adverse effects of long-term cadmium exposure persist into cadmium free conditions, as seen by non-monotonic responses when exposed to novel stress one generation removed.

      Full Text Available Segundo a abordagem etnopsicológica, as premissas histórico-socioculturais, que constituem crenças inquestionáveis consensualmente aceitas por um grupo social, desempenham papel chave na compreensão do comportamento individual. Apoiando-se nessa perspectiva, investigou-se a influência do sexo e idade no grau de adesão a premissas sobre a família brasileira. A amostra compreendeu 393 sujeitos de ambos os sexos, distribuídos em quatro faixas etárias, que responderam à adaptação brasileira do Questionário sobre a Estrutura da Família Mexicana. Os homens endossaram mais fortemente que as mulheres as premissas associadas à dominação masculina, valores tradicionais da família e virgindade feminina. As mulheres revelaram-se mais tradicionais que os homens na aceitação das premissas relacionadas à abnegação feminina. Não foram observadas diferenças entre os grupos de idade em nenhuma das dimensões consideradas. Concluiu-se que, embora a sociedade brasileira venha sofrendo mudanças, os valores e crenças sobre a família, introjetados pelos homens e pelos mais jovens, não acompanharam essas mudanças.In the ethnopsychological approach, historic-sociocultural premises, which are unquestionable beliefs consensually accepted by a social group, play a key role in the understanding of individual behavior.

      Outbreeding, mating between genetically divergent individuals, may result in negative fitness consequences for offspring via outbreeding depression. Outbreeding effects are of notable concern in salmonid research as outbreeding can have major implications for salmon aquaculture and conservation management. We therefore quantified outbreeding effects in two generations (F1 hybrids and F2 backcrossed hybrids) of Chinook salmon (Oncorhynchus tshawytscha) derived from captively-reared purebred lines that had been selectively bred for differential performance based on disease resistance and growth rate. Parental lines were crossed in 2009 to create purebred and reciprocal hybrid crosses (n = 53 families), and in 2010 parental and hybrid crosses were crossed to create purebred and backcrossed hybrid crosses (n = 66 families). Although we found significant genetic divergence between the parental lines (FST = 0.130), reciprocal F1 hybrids showed no evidence of outbreeding depression (hybrid breakdown) or favorable heterosis for weight, length, condition or survival. The F2 backcrossed hybrids showed no outbreeding depression for a suite of fitness related traits measured from egg to sexually mature adult life stages. Our study contributes to the current knowledge of outbreeding effects in salmonids and supports the need for more research to better comprehend the mechanisms driving outbreeding depression.

      Reproductive toxicity of Atrazine (ATR) was evaluated in two rat multigenerational studies. Development of male reproductive parameters was evaluated in separate studies after prenatal or postnatal exposure. In multigenerational studies, rats received dietary concentrations of 0, 10, 50, 100 or 500 ppm ATR. In separate studies in female rats, ATR was administered by gavage at 0, 1, 5, 25 or 125 mg/kg/day during pregnancy (GD6-21) or lactation (LD2-21). Plasma testosterone concentration, testicular and epididymal weights, and sperm counts were measured in male offspring on PND70 and 170. In the multigenerational studies, parental systemic toxicity occurred at 500 ppm (38.7 mg/kg/day), but reproductive endpoints were unaffected. In the prenatal study, maternal toxicity and embryo-fetal mortality occurred at 125 mg/kg/day. In male offspring, testosterone levels and sperm counts were unaffected, although the percentage of abnormal sperm increased at 125 mg/kg/day (PND 70) and 25 mg/kg/day (PND170). In the postnatal study, maternal toxicity and reduced body weights of male offspring occurred at 125 mg/kg/day. Additionally, reduced testicular (PND70, PND170) and epididymal (PND70) weights and increased numbers of abnormal sperm (PND70, PND170) were seen, but no changes in plasma testosterone or sperm counts. Dietary administration of ATR did not affect rat reproduction up to a parentally toxic dose of 38.7 mg/kg/day. Some effects on male reproductive system development occurred after high dose, bolus administration to dams, but doses were much higher than expected under normal use conditions. Thus, oral RfDs for ATR would be protective for reproductive effects. © 2014 Wiley Periodicals, Inc.

      To evaluate the effects of propranolol on Daphnia magna (D. magna), we employed a multi-generational exposure period for eight generations and an environmentally relevant low concentration with 1.5 ng/L, 0.2 μg/L and 26 μg/L to reflect a realistic exposure scenario. Physiological endpoints were checked, including growth, number of neonates, heart rate, frequency of abdominal appendage movement and malformation rate of neonates. In the results, growth and abdominal appendage movement were affected by environmental concentration during several generations, and the responses showed consistent tendencies of response increase with concentration increase. Heart rate was the only endpoint affected throughout all exposure generations. Inhibitory and acceleratory effects on heart rate, growth and abdominal appendage movement suggest that it is necessary to cover sub-lethal endpoints of non-targeted organisms in eco-toxicity study because the physiological responses were detected at much lower concentrations than the results of traditional toxicity tests, including environmental concentration. - Highlights: • Multi-generational exposure was conducted to evaluate the effect of propranolol on Daphnia magna. • Heart rate was the only endpoint affected throughout all exposure generations. • Growth and abdominal appendage movement were affected at environmental concentrations. • Time series fluctuations in responses appeared with no tendencies throughout all generations. • It is necessary to cover sub-organismal endpoints and long-term exposure in ecotoxicity test. - Heart rate, growth and abdominal appendage movement of D. magna were affected by the multigenerational exposure of propranolol at environmental levels.

      Highlights: • Clofibric acid (CA) induces multigenerational effects in zebrafish (Danio rerio). • CA impacts fish lipid metabolism, with similarities to those reported in mammals. • Weight is impacted in F1 and F2 generations, thought with opposite patterns. - Abstract: Clofibric acid (CA) is an active metabolite of the blood lipid lowering agent clofibrate, a pharmaceutical designed to work as agonist of peroxisome proliferator-activated receptor alpha (PPARa). It is the most commonly reported fibrate in aquatic environments with low degradation rate and potential environmental persistence. Previous fish exposures showed that CA may impact spermatogenesis, growth and the expression of fat binding protein genes. However, there are limited data on the effects of chronic multigenerational CA exposures. Here, we assessed chronic multigenerational effects of CA exposure using zebrafish (Danio rerio) as a teleost model. Zebrafish were exposed through the diet to CA (1 and 10 mg/g) during their whole lifetime. Growth, reproduction-related parameters and embryonic development were assessed in the exposed fish (F1 generation) and their offspring (F2 generation), together with muscle triglyceride content and gonad histology. In order to study the potential underlying mechanisms, the transcription levels of genes coding for enzymes involved in lipid metabolism pathways were determined. The results show that chronic life-cycle exposure to CA induced a significant reduction in growth of F1 generation and lowered triglyceride muscle content (10 mg/g group). Also, an impact in male gonad development was observed together with a decrease in the fecundity (10 mg/g group) and higher frequency of embryo abnormalities in the offspring of fish exposed to the lowest CA dose. The profile of the target genes was sex- and tissue-dependent. In F1 an up-regulation of male hepatic pparaa, pparb and acox transcript levels was observed, suggesting an activation of the fatty acid

Zebrafish were exposed through the diet to CA (1 and 10 mg/g) during their whole lifetime. Growth, reproduction-related parameters and embryonic development were assessed in the exposed fish (F1 generation) and their offspring (F2 generation), together with muscle triglyceride content and gonad histology. In order to study the potential underlying mechanisms, the transcription levels of genes coding for enzymes involved in lipid metabolism pathways were determined. The results show that chronic life-cycle exposure to CA induced a significant reduction in growth of F1 generation and lowered triglyceride muscle content (10 mg/g group). Also, an impact in male gonad development was observed together with a decrease in the fecundity (10 mg/g group) and higher frequency of embryo abnormalities in the offspring of fish exposed to the lowest CA dose. The profile of the target genes was sex- and tissue-dependent. In F1 an up-regulation of male hepatic pparaa, pparb and acox transcript levels was observed, suggesting an activation of the fatty acid

      The multigenerational survival rate for family-owned businesses is not good. Lack of a shared vision for the family enterprise and weak next-generation leadership are often cited as two of the leading reasons for the failure of family firms to successfully transition from one generation of family ownership to the next. The climate of the business-owning family has also been suggested as important to the performance of the family enterprise. Despite these commonly held tenets, there is a la...

    6. Multi-Generation Concentrating Solar-Hydrogen Power System for Sustainable Rural Development

      Energy Technology Data Exchange (ETDEWEB)

      Krothapalli, A.; Greska, B.

      2007-07-01

      This paper describes an energy system that is designed to meet the demands of rural populations that currently have no access to grid-connected electricity. Besides electricity, it is well recognized that rural populations need at least a centralized refrigeration system for storage of medicines and other emergency supplies, as well as safe drinking water. Here we propose a district system that will employ a multi-generation concentrated solar power (CSP) system that will generate electricity and supply the heat needed for both absorption refrigeration and membrane distillation (MD) water purification. The electricity will be used to generate hydrogen through highly efficient water electrolysis and individual households can use the hydrogen for generating electricity, via affordable proton exchange membrane (PEM) fuel cells, and as a fuel for cooking. The multi-generation system is being developed such that its components will be easy to manufacture and maintain. As a result, these components will be less efficient than their typical counterparts but their low cost-to-efficiency ratio will allow for us to meet our installation cost goal of $1/Watt for the entire system. The objective of this paper is to introduce the system concept and discuss the system components that are currently under development. (auth)

      Full Text Available The use of biomass due to the reduction in greenhouse gas emissions and environmental impacts has attracted many researchers’ attention in the recent years. Access to an energy conversion system which is able to have the optimum performance for applying valuable low heating value fuels has been considered by many practitioners and scholars. This paper focuses on the accurate modeling of biomass gasification process and the optimal design of a multigeneration system (heating, cooling, electrical power, and hydrogen as energy carrier to take the advantage of this clean energy. In the process of gasification modeling, a thermodynamic equilibrium model based on Gibbs energy minimization is used. Also, in the present study, a detailed parametric analysis of multigeneration system for undersigning the behavior of objective functions with changing design parameters and obtaining the optimal design parameters of the system is done as well. The results show that with exergy efficiency as an objective function this parameter can increase from 19.6% in base case to 21.89% in the optimized case. Also, for the total cost rate of system as an objective function it can decrease from 154.4 $/h to 145.1 $/h.

      Although it is well known that post-abortion contraceptive use is high when family planning services are provided following spontaneous or induced abortions, this relationship remains unclear in Brazil and similar settings with restrictive abortion laws. Our study aims to assess whether contraceptive use is associated with access to family planning services in the six-month period post-abortion, in a setting where laws towards abortion are highly restrictive. This prospective cohort study recruited 147 women hospitalized for emergency treatment following spontaneous or induced abortion in Brazil. These women were then followed up for six months (761 observations). Women responded to monthly telephone interviews about contraceptive use and the utilization of family planning services (measured by the utilization of medical consultation and receipt of contraceptive counseling). Generalized Estimating Equations were used to analyze the effect of family planning services and other covariates on contraceptive use over the six-month period post-abortion. Women who reported utilization of both medical consultation and contraceptive counseling in the same month had higher odds of reporting contraceptive use during the six-month period post-abortion, when compared with those who did not use these family planning services [adjusted aOR = 1.93, 95 % Confidence Interval: 1.13-3.30]. Accessing either service alone did not contribute to contraceptive use. Age (25-34 vs. 15-24 years) was also statistically associated with contraceptive use. Pregnancy planning status, desire to have more children and education did not contribute to contraceptive use. In restrictive abortion settings, family planning services offered in the six-month post-abortion period contribute to contraceptive use, if not restricted to simple counseling. Medical consultation, in the absence of contraceptive counseling, makes no difference. Immediate initiation of a contraceptive that suits women's pregnancy

      Clofibric acid (CA) is an active metabolite of the blood lipid lowering agent clofibrate, a pharmaceutical designed to work as agonist of peroxisome proliferator-activated receptor alpha (PPARa). It is the most commonly reported fibrate in aquatic environments with low degradation rate and potential environmental persistence. Previous fish exposures showed that CA may impact spermatogenesis, growth and the expression of fat binding protein genes. However, there are limited data on the effects of chronic multigenerational CA exposures. Here, we assessed chronic multigenerational effects of CA exposure using zebrafish (Danio rerio) as a teleost model. Zebrafish were exposed through the diet to CA (1 and 10mg/g) during their whole lifetime. Growth, reproduction-related parameters and embryonic development were assessed in the exposed fish (F1 generation) and their offspring (F2 generation), together with muscle triglyceride content and gonad histology. In order to study the potential underlying mechanisms, the transcription levels of genes coding for enzymes involved in lipid metabolism pathways were determined. The results show that chronic life-cycle exposure to CA induced a significant reduction in growth of F1 generation and lowered triglyceride muscle content (10mg/g group). Also, an impact in male gonad development was observed together with a decrease in the fecundity (10mg/g group) and higher frequency of embryo abnormalities in the offspring of fish exposed to the lowest CA dose. The profile of the target genes was sex- and tissue-dependent. In F1 an up-regulation of male hepatic pparaa, pparb and acox transcript levels was observed, suggesting an activation of the fatty acid metabolism (provided that transcript level change indicates also a protein level change). Interestingly, the F2 generation, raised with control diet, displayed a response pattern different from that observed in F1, showing an increase in weight in the descendants of CA exposed fish, in

      2014-01-01

      Full Text Available OBJECTIVE: To evaluate the association between the consumption of psychoactive substances (tobacco, alcohol and illicit drugs and demographic variables, mental health and family context among school-aged children. METHODS: The National Adolescent School-based Health Survey was held with a national sample of 109,104 students. Data regarding demographic variables, family background and mental health were collected. Logistic regression was used to evaluate the associations of interest. RESULTS: Multivariate analyses showed that alcohol consumption was higher among girls, drug experimentation was more frequent among boys and that there was no difference between sexes for smoking. Being younger and mulatto were negatively associated with the use of tobacco, alcohol and illicit drugs. Also negatively associated with such risk behaviors were characteristics of the family context represented by: living with parents, having meals together and parental supervision (when parents know what the child does in their free time. Moreover, characteristics of mental health such as loneliness and insomnia were positively associated with use of tobacco, alcohol and illicit drugs. Not having friends was positively associated with use of tobacco and illicit drugs and negatively associated with alcohol use. CONCLUSIONS: The study shows the protective effect of family supervision in the use of tobacco, alcohol and drugs and, on the contrary, the increasing use of substances according to aspects of mental health, such as loneliness, insomnia and the fact of not having friends. The study's findings may support actions from health and education professionals, as well as from the government and families in order to prevent the use of these substances by adolescents.

      Intrauterine growth restriction (IUGR) confers heritable alterations in DNA methylation, rendering risk of adult metabolic syndrome (MetS). Because CpG methylation is coupled to intake of essential nutrients along the one-carbon pathway, we reasoned that essential nutrient supplementation (ENS) may abrogate IUGR-conferred multigenerational MetS. Pregnant Sprague-Dawley rats underwent bilateral uterine artery ligation causing IUGR in F1. Among the F2 generation, IUGR lineage rats were underweight at birth (6.7 vs. 8.0 g, P 30% elevated, P 5-fold less central fat mass, normal hepatic glucose efflux, and >70% reduced circulating triglycerides and very-LDLs compared with IUGR control-fed F2 offspring (P intrauterine growth-restricted rats.

      1986-01-01

      The occurrence of a heritable, multiple intestinal adenocarcinoma (HMIA) was observed in the offspring of an outcross between a male (or female) parent originating from our C57 Black/6M strain and his female (or male) mating counterpart originating from an experimental subline of the same strain, propagated with multigeneration exposure of the male parent to low-level tritium. Multiple intestinal malignancy was observed with a high-expression frequency in all animals examined in five subsequent generations, irrespective of the sex of the initial ascendant originating from the experimental subline, exposed to tritiated water. A digenic inheritance with partial penetrance is postulated, involving at least a two-stage process of tumorigenesis, namely, a dominant mutation at one locus and a second mutation to a recessive which, as long as it remained homozygous, prevented expression of the tumorigenic dominant gene. 10 refs., 2 tabs

      Full Text Available A genome-wide linkage scan was conducted in a Northern-European multigenerational pedigree with nine of 40 related members affected with concomitant strabismus. Twenty-seven members of the pedigree including all affected individuals were genotyped using a SNP array interrogating > 300,000 common SNPs. We conducted parametric and non-parametric linkage analyses assuming segregation of an autosomal dominant mutation, yet allowing for incomplete penetrance and phenocopies. We detected two chromosome regions with near-suggestive evidence for linkage, respectively on chromosomes 8 and 18. The chromosome 8 linkage implied a penetrance of 0.80 and a rate of phenocopy of 0.11, while the chromosome 18 linkage implied a penetrance of 0.64 and a rate of phenocopy of 0. Our analysis excludes a simple genetic determinism of strabismus in this pedigree.

      This paper presents a novel, simple method for reducing external operating condition datasets to be used in multi-generation system optimization models. The method, called the Characteristic Operating Pattern (CHOP) method, is a visually-based aggregation method that clusters reference data based...... on parameter values rather than time of occurrence, thereby preserving important information on short-term relations between the relevant operating parameters. This is opposed to commonly used methods where data are averaged over chronological periods (months or years), and extreme conditions are hidden...... in the averaged values. The CHOP method is tested in a case study where the operation of a fictive Danish combined heat and power plant is optimized over a historical 5-year period. The optimization model is solved using the full external operating condition dataset, a reduced dataset obtained using the CHOP...

      To evaluate the profile of food acquisition in the National School Feeding Program according to the extent and purpose of food processing in three municipalities of southern Brazil during the implementation period of Law 11.947/2009. Descriptive cross-sectional study. Data for 2008-2010 involved quantities, prices and types of suppliers for food items purchased. In total, 1529 purchases were analysed. The items were classified into the following groups: G1 (unprocessed/minimally processed), G2 (culinary ingredients), G3 (processed), G4 (ultra-processed). Quantities of purchased foods were converted into energy and average prices ($US/4184 kJ (1000 kcal)) were calculated. The proportion of each food group in total purchases was expressed as both a percentage of total energy and a percentage of total expenditure. Data analysis was carried out in Stata version 12.1. Three municipalities in southern Brazil. Relative contribution to total energy purchased was high for G1 (49·8 %; G2, 23·8 %; G3, 4·5 %; G4, 21·8 %). Among acquisitions from family farming, G1 represented 51·3 % of the total energy purchased; G2, 9·9 %; G3, 19·7 %; G4, 19·0 %. Total cost was as follows: G1, 61·6 %; G2, 3·9 %; G3, 18·5 %; G4, 16·0 %. Prices for food products from family farms were consistently higher. Average price from family farms was 1·3; from conventional suppliers, 0·9. The implementation of Law 11.947/2009 produced a positive effect on the regional profile of food purchases for the School Feeding Program. However, there is still considerable potential to promote health by strengthening relationships between family farming and school feeding.

      The cladoceran Daphnia magna was acclimated for seven generations to cadmium concentrations ranging from 0 (control) to 250 μg/l Cd (corresponding to a free ion activity of 4.60 nM Cd 2+ ). Acute and chronic cadmium tolerance as well as cadmium accumulation were monitored as a function of acclimation time. After two to three generations of acclimation to concentrations ranging from 0.23 to 1.11 nM Cd 2+ increases in acute tolerance were maximal (factor 7.2) and significant. Acclimation for seven generations to the same acclimation concentrations did result in an increased chronic cadmium tolerance (21 days EC 50 values increased). Organisms acclimated to 1.93 nM Cd 2+ were equally or more sensitive than non-acclimated daphnids in acute and chronic toxicity tests. Cadmium contents in D. magna increased significantly as a function of the acclimation concentration. Maximum body burdens of 236±30 μg Cd/g dry weight were measured in organisms exposed to 4.60 nM Cd 2+ , but detoxification mechanisms were only successful up to 82±20 μg Cd/g dry weight as this concentration did not cause major decreases in survival and reproduction in chronic toxicity tests. As the potential positive effect of acclimation on cadmium tolerance disappeared with successive acclimation generations and increasing acclimation concentrations, it is concluded that multi-generation acclimation studies are important for the evaluation of the long-term effects of environmental toxicants. - Multi-generation acclimation studies are important for evaluating long-term effects of aquatic pollutants

      In this study, a thermodynamic analysis is conducted on a multigeneration energy system based on renewable energy sources. The proposed system is developed for residential applications, including individual- and multi-building complexes, utilizing solar energy to produce useful outputs, namely electricity, heat, fresh water and hydrogen. Hydrogen is used for the purpose of storing energy to offset the mismatch between demand and supply when dealt with renewables, such as solar energy. The system is modeled thermodynamically to obtain the optimal energy and exergy efficiencies, heat and work outputs for the overall system. Moreover, greenhouse gas emissions caused by conventional energy systems utilized for the same outputs are calculated and compared with the studied systems. A solar collector area of 24 m 2 is considered for the present system and its analysis. The maximum energy efficiency is 36% and the maximum exergy efficiency is 44%. The total work output for electricity is 116 kW, and hence the CO 2 reduction achieved by this system is 476 tons per year. It can produce 0.04 kg/s desalinated water. The optimum number of suites, as an application for a building complex, which can be sustained with the proposed system is determined as 106 suites. - Highlights: • A solar energy based multigeneration system is proposed. • Energy, exergy efficiencies, heat, work outputs of the system are determined. • Optimization is done on efficiencies and work output. • Domestic heating, desalination, hydrogen, electricity is obtained. • Overall system energy and exergy efficiency is found to be 36% and 44%.

      The Bolsa Família Program was created in Brazil in 2003, by the joint of different social programs aimed at poor or very poor families with focus on income transfer to promote immediate poverty relief, conditionalities and complementary programs. Given the contributions of conditional cash transfer programs to poverty alleviation and their potential effects on nutrition and health, the objective of this study was to assess the impact of the Bolsa Família Program on food purchases of low-income households in Brazil. Representative data from the Household Budget Survey conducted in 2008-2009 were studied, with probabilistic sample of 55,970 households. 11,282 households were eligible for this study and 48.5 % were beneficiaries of the BFP. Food availability indicators were compared among paired blocks of households (n = 100), beneficiaries or non-beneficiaries of the Bolsa Família Program, with monthly per capita income up to R$ 210.00. Blocks of households were created based on the propensity score of each household to have beneficiaries and were homogeneous regarding potential confounding variables. The food availability indicators were weekly per capita expenditure and daily energy consumption, both calculated considering all food items and four food groups based on the extent and purpose of the industrial food processing. The comparisons between the beneficiaries and non-beneficiaries blocks of households were conducted through paired 't' tests. Compared to non-beneficiaries, the beneficiaries households had 6 % higher food expenditure (p = 0.015) and 9.4 % higher total energy availability (p = 0.010). It was found a 7.3 % higher expenditure on in natura or minimally processed foods and 10.4 % higher expenditure on culinary ingredients among the Bolsa Família Program families. No statistically significant differences were found regarding the expenditure and the availability of processed and ultra-processed food and drink products. In the in

      In this paper, a geothermal based multi-generation energy system, including organic Rankine cycle, domestic water heater, absorption refrigeration cycle and proton exchange membrane electrolyzer, is developed to generate electricity, heating, cooling and hydrogen. For this purpose, energetic, exergetic and exergoeconomic analysis are undertaken upon proposed system. Also, the effects of some important variables, i.e. geothermal water temperature, turbine inlet temperature and pressure, generator temperature, geothermal water mass flow rate and electrolyzer current density on the several parameters such as energy and exergy efficiencies of the proposed system, heating and cooling load, net electrical output power, hydrogen production, unit cost of each system products and total unit cost of the products are investigated. For specified conditions, the results show that energy and exergy efficiencies of the proposed multi-generation system are calculated about 34.98% and 49.17%, respectively. The highest and lowest total unit cost of the products estimated approximately 23.18 and 22.73 $/GJ, respectively, by considering that geothermal water temperature increases from 185 °C to 215 °C. - Highlights: • A multigeneration energy system based on geothermal energy is developed. • The energetic, exergetic and exergoeconomic analysis are undertaken upon proposed system. • The influences of several significant parameters are investigated. • The energy and exergy efficiencies of the entire system are calculated around 34.98% and 49.17%.

      To document the clinical characteristics and inheritance pattern of epilepsy in multigeneration Algerian families. Affected members from extended families with familial epilepsy were assessed at the University Hospital of Oran in Algeria. Available medical records, neurological examination, electroencephalography and imaging data were reviewed. The epilepsy type was classified according to the criteria of the International League Against Epilepsy and modes of inheritance were deduced from pedigree analysis. The study population included 40 probands; 23 male (57.5%) and 17 female subjects (42.5%). The mean age of seizure onset was 9.5 ± 6.1 years. According to seizure onset, 16 patients (40%) had focal seizures and 20 (50%) had generalized seizures. Seizure control was achieved for two patients (5%) for 10 years, while 28 (70%) were seizure-free for 3 months. Eleven patients (27.5%) had prior febrile seizures, 12 were diagnosed with psychiatric disorders and four families had syndromic epilepsy. The consanguinity rate among parents of affected was 50% with phenotypic concordance observed in 25 families (62.5%). Pedigree analysis suggested autosomal dominant (AD) inheritance with or without reduced penetrance in 18 families (45%), probable autosomal recessive (AR) inheritance in 14 families (35%), and an X-linked recessive inheritance in one family. This study reveals large Algerian families with multigenerational inheritance of epilepsy. Molecular testing such as exome sequencing would clarify the genetic basis of epilepsy in some of our families. Copyright © 2015 British Epilepsy Association. Published by Elsevier Ltd.

      Full Text Available The spinocerebellar ataxias (SCAs are a clinically and genetically heterogeneous group of late onset neurodegenerative disorders. To date, seven different genes causing autosomal dominant SCA have been mapped: SCA1, SCA2, Machado-Joseph disease (MJD/SCA3, SCA4, SCA5, SCA7 and dentatorubropallidoluysian atrophy (DRPLA. Expansions of an unstable trinucleotide CAG repeat cause three of these disorders: SCA1, MJD/SCA3 and DRPLA. We studied one Brazilian family segregating an autosomal dominant type of SCA. A total of ten individuals were examined and tested for the presence of the SCA1, MJD and DRPLA mutations. Three individuals, one male and two females, were considered affected based on neurological examination; ages at onset were: 32, 36 and 41 years. The first complaint in all three patients was gait ataxia which progressed slowly over the years. Six individuals showed one allele containing an expanded CAG repeat in the SCA1 gene. The mean size of the expanded allele was 48.2 CAG units. Instability of the expanded CAG tract was seen in the two transmissions that were observed in this family. In both occasions there was a contraction of the CAG tract. Our study demonstrates that SCA1 occurs in the Brazilian population. In addition, our results stress the importance of molecular studies in the confirmation of diagnosis and for pre-symptomatic testing in SCAs.As ataxias espinocerebelares (AECs fazem parte de um grupo de doenças neurodegenerativas que apresentam grande heterogeneidade clínica e genética.

    11. Zombie projects, negative networks, and multigenerational science: The temporality of the International Map of the World.

      The International Map of the World was a hugely ambitious scheme to create standardized maps of the entire world. It was first proposed in 1891 and remained a going concern until 1986. Over the course of the project's official life, nearly every country in the world took part, and map sheets were published showing all but a few areas of the planet. But the project ended quite unceremoniously, repudiated by cartographers and mapping institutions alike, and it is now remembered as a 'sad story' of network failure. How can we evaluate this kind of sprawling, multigenerational project? In order to move beyond practitioners' (and historians') habit of summarizing the entire endeavor using the blunt categories of success and failure, I propose a more temporally aware reading, one that both disaggregates the (persistent) project from the (always changing) network and sees project and network as invertible, with the possibility of zombie projects and negative networks that can remain robust even when disconnected from their original goals. I therefore see the abandonment of the International Map of the World as resulting from vigorous collaboration and new norms in cartography, not from lack of cooperation or other resources. New categories are required for analyzing science over the long durée.

      The brown planthopper (BPH), Nilaparvata lugens, is one of the most devastating rice pests in Asia. Resistant cultivars are an effective way of managing BPH. Bph15 is a BPH resistance gene and has been introgressed into rice variety Minghui 63 (MH63). The multi-generational effects of rice line MH63::15 (harboring Bph15) on BPH were investigated and compared with its parental line MH63. U-test analysis indicated that, over seven generations, the developmental duration of BPH nymphs was significantly prolonged by MH63::15. The results of a two-way analysis indicated that, over seven generations, MH63::15 had significant negative effects on the hatchability, emergence rate, copulation rate, weight of adults and fecundity of BPH, but no significant effects on the survival rate of nymphs or female ratio of BPH. In addition, the development of ovary was significantly retarded by MH63::15, and the expression of oogenesis genes were either down-regulated (three genes) or up-regulated (one genes) by MH63::15 compared with MH63. After being reared continuously on MH63::15 for seven generations, most of the life parameters of BPH were negatively affected by MH63::15, especially fecundity and ovary development. These results indicate that MH63::15 rice has potential for use in the control of BPH. © 2013 Society of Chemical Industry.

      Dallas-Fort Worth Metroplex (DFW) has a population of over 7 million depending on many water supply reservoirs. The reservoir inflow plays a vital role in water supply decision making process and long-term strategic planning for the region. This paper demonstrates a method of utilizing deep learning algorithms and multi-general circulation model (GCM) platform to forecast reservoir inflow for three reservoirs within the DFW: Eagle Mountain Lake, Lake Benbrook and Lake Arlington. Ensemble empirical mode decomposition was firstly employed to extract the features, which were then represented by the deep belief networks (DBNs). The first 75 years of the historical data (1940 -2015) were used to train the model, while the last 2 years of the data (2016-2017) were used for the model validation. The weights of each DBN gained from the training process were then applied to establish a neural network (NN) that was able to forecast reservoir inflow. Feature predictors used for the forecasting model were generated from weather forecast results of the downscaled multi-GCM platform for the North Texas region. By comparing root mean square error (RMSE) and mean bias error (MBE) with the observed data, the authors found that the deep learning with downscaled multi-GCM platform is an effective approach in the reservoir inflow forecasting.

    14. Does multigenerational exposure to hormetic concentrations of imidacloprid precondition aphids for increased insecticide tolerance?

      Hormetic preconditioning, whereby exposure to mild stress primes an organism to better tolerate subsequent stress, is well documented. It is unknown if exposure to hormetic concentrations of insecticide can trans-generationally prime insects to better tolerate insecticide exposure, or whether exposure to hormetic concentrations of insecticide can induce mutations in genes responsible for insecticide resistance. Using the aphid Myzus persicae (Sulzer) and the insecticide imidacloprid as a model, we examined if exposure to mildly toxic and hormetic concentrations of imidacloprid reduced aphid susceptibility to insecticides across four generations, and whether such exposures induced mutations in the imidacloprid binding site in post-synaptic nicotinic acetylcholine receptors. Chronic, multigenerational exposure of aphids to hormetic concentrations of imidacloprid primed offspring to better survive exposure to certain concentrations of imidacloprid, but not exposure to spirotetramat, an insecticide with a different mode of action. Exposure to hormetic and mildly toxic concentrations of imidacloprid did not result in mutations in any of the examined nicotinic acetylcholine receptor subunits. Our findings demonstrate that exposure to hormetic concentrations of insecticide can prime insects to better withstand subsequent chemical stress, but this is dependent upon the insecticide exposure scenario, and may be subtle over generations. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

      Knowledge of airflow patterns in the human lung is important for an analysis of lung diseases and drug delivery of aerosolized medicine for medical treatment. However, very little systematic information is available on the pattern of airflow in the lung and on how this pattern affects the deposition of toxicants in the lung, and the efficacy of aerosol drug therapy. Most previous studies have only considered the airflow through a single bifurcating airway. However, the flow in a network of more than one bifurcation is more complicated due to the effect of interrelated lung generations. Because of the variation of airway geometry and flow condition from generation to generation, a single bifurcating airway cannot be taken as a representative for the others in different generations. The flow in the network varies significantly with airway generations because of a redistribution of axial momentum by the secondary flow motions. The influence of the redistribution of flow is expected in every generation. Therefore, a systematic information of the airflow through a multi-generation tracheobronchial conducting airway is needed, and it becomes the purpose of this study. This study has provided information on airflow in a lung model which is necessary to the study of the deposition of toxicants and therapeutic aerosols

      The early introduction of non-milk foods among African-American infants has been well documented. Several studies report the addition of semi-solids as early as 1-2 weeks of age. This study investigated, through ethnographic, repeat indepth interviews with teen mothers and grandmothers of infants, the determinants of such feeding practices and the inter-generational factors involved in infant feeding decision-making. Nineteen adolescent mothers were recruited from Baltimore City WIC programs. The teen mothers were interviewed in their homes during four separate visits and the grandmothers at least twice. Ethnographic field guides focused on questions about what, why and how infants were fed and on the 'ethnotheories' of parenting and infant care in this population. All interviews were taped and transcripts were analyzed using text retrieval software. Results confirmed that it is the cultural norm to feed cereal in the bottle and to feed other semi-solid foods within the first month of life. Most grandmothers played the dominant role in deciding what the infant should eat and the timing of the introduction of solids. This pattern occurred both because grandmothers had extensive physical access to their grandchildren and because teen mothers were dependent upon grandmothers. The use of qualitative research methods, with an ecological, multi-generational focus, provides a rich description of the context within which infant feeding decisions are made.

      Insect migration may involve movements over multiple breeding generations at continental scales, resulting in formidable challenges to their conservation and management. Using distribution models generated from citizen scientist occurrence data and stable-carbon and -hydrogen isotope measurements, we tracked multi-generational colonization of the breeding grounds of monarch butterflies (Danaus plexippus) in eastern North America. We found that monarch breeding occurrence was best modelled with geographical and climatic variables resulting in an annual breeding distribution of greater than 12 million km2 that encompassed 99% occurrence probability. Combining occurrence models with stable isotope measurements to estimate natal origin, we show that butterflies which overwintered in Mexico came from a wide breeding distribution, including southern portions of the range. There was a clear northward progression of monarchs over successive generations from May until August when reproductive butterflies began to change direction and moved south. Fifth-generation individuals breeding in Texas in the late summer/autumn tended to originate from northern breeding areas rather than regions further south. Although the Midwest was the most productive area during the breeding season, monarchs that re-colonized the Midwest were produced largely in Texas, suggesting that conserving breeding habitat in the Midwest alone is insufficient to ensure long-term persistence of the monarch butterfly population in eastern North America.

      It has been proposed that languages evolve by adapting to the perceptual and cognitive constraints of the human brain, developing, in the course of cultural transmission, structural regularities that maximize or optimize learnability and ease of processing. To what extent would perceptual and cognitive constraints similarly affect the evolution of musical systems? We conducted an experiment on the cultural evolution of artificial melodic systems, using multi-generational signaling games as a laboratory model of cultural transmission. Signaling systems, using five-tone sequences as signals, and basic and compound emotions as meanings, were transmitted from senders to receivers along diffusion chains in which the receiver in each game became the sender in the next game. During transmission, structural regularities accumulated in the signaling systems, following principles of proximity, symmetry, and good continuation. Although the compositionality of signaling systems did not increase significantly across generations, we did observe a significant increase in similarity among signals from the same set. We suggest that our experiment tapped into the cognitive and perceptual constraints operative in the cultural evolution of musical systems, which may differ from the mechanisms at play in language evolution and change.

      Brazil is a country of continental dimensions with a large heterogeneity of climates and massive mixing of the population. Almost the entire national territory is located between the Equator and the Tropic of Capricorn, and the Earth axial tilt to the south certainly makes Brazil one of the countries of the world with greater extent of land in proximity to the sun. The Brazilian coastline, where most of its population lives, is more than 8,500 km long. Due to geographic characteristics and cultural trends, Brazilians are among the peoples with the highest annual exposure to the sun. Epidemiological data show a continuing increase in the incidence of non-melanoma and melanoma skin cancers. Photoprotection can be understood as a set of measures aimed at reducing sun exposure and at preventing the development of acute and chronic actinic damage. Due to the peculiarities of Brazilian territory and culture, it would not be advisable to replicate the concepts of photoprotection from other developed countries, places with completely different climates and populations. Thus the Brazilian Society of Dermatology has developed the Brazilian Consensus on Photoprotection, the first official document on photoprotection developed in Brazil for Brazilians, with recommendations on matters involving photoprotection.

      Full Text Available Because of reproductions and hormone changes, females are more sensitive to bone mineral loss during their lifetime. Bottled water has become more popular in recent years, and a large number of products are low mineral water. However, research on the effects of drinking bottled low mineral water on bone health is sparse.To elucidate the skeletal effects of multi-generational bottled water drinking in female rats.Rats continuously drank tap water (TW, bottled natural water (bNW, bottled mineralized water (bMW, or bottled purified water (bPW for three generations.The maximum deflection, elastic deflection, and ultimate strain of the femoral diaphysis in the bNW, bMW, and bPW groups and the fracture strain in the bNW and bMW groups were significantly decreased. The tibiae calcium levels in both the bNW and bPW groups were significantly lower than that in the TW group. The tibiae and teeth magnesium levels in both the bNW and bPW groups were significantly lower than those in the TW group. The collagen turnover markers PICP (in both bNW and bPW groups were significantly lower than that in the TW group. In all three low mineral water groups, the 1,25-dihydroxy-vitamin D levels were significantly lower than those in the TW group.Long-term drinking of low mineral water may disturb bone metabolism and biochemical properties and therefore weaken biomechanical bone properties in females. Drinking tap water, which contains adequate minerals, was found to be better for bone health. To our knowledge, this is the first report on drinking bottled low mineral water and female bone quality on three generation model.

      Tris(2-butoxyethyl) phosphate (TBOEP) is an organophosphate ester used as substitute following the phase-out of brominated flamed retardants. Because of its high production volume and its use in a broad range of applications, this chemical is now frequently detected in the environment and biota. However, limited information is available on the long-term effects of TBOEP in aquatic organisms. In this study, Daphnia magna were exposed over three 21d generations to an environmentally relevant concentration of TBOEP (10μg/L) and effects were evaluated at the gene transcription, protein, and life-history (i.e., survival, reproduction and growth) levels. Chronic exposure to TBEOP did not impact survival or reproduction of D. magna but affected the growth output. The mean number of molts was also found to be lower in daphnids exposed to the chemical compared to control for a given generation, however there were no significant differences over the three generations. Molecular responses indicated significant differences in the transcription of genes related to growth, molting, ecdysteroid and juvenile hormone signaling, proteolysis, oxidative stress, and oxygen transport within generations. Levels of mRNA were also found to be significantly different for genes known to be involved in endocrine-mediated mechanisms such as reproduction and growth between generations F0, F1, and F2, indicating effects of parental exposure on offspring. Transcription results were supported by protein analyses with the significant decreased in catalase (CAT) activity in F1 generation, following the decreased transcription of cat in the parental generation. Taken together, these multi-biological level results suggest long-term potential endocrine disruption effects of TBOEP in D. magna exposed to an environmentally relevant concentration. This study highlights the importance of using chronic and multigenerational biological evaluation to assess risks of emerging chemicals. Crown Copyright

      Full Text Available Subsynchronous oscillation (SSO of generators caused by high voltage direct current (HVDC systems can be solved by applying supplemental subsynchronous damping controller (SSDC. SSDC application in mitigating SSO of single-generator systems has been studied intensively. This paper focuses on SSDC application in mitigating SSO of multi-generator systems. The phase relationship of the speed signals of the generators under their common mechanical natural frequencies is a key consideration in SSDC design. The paper studies in detail the phase relationship of the speed signals of two generators in parallel under their shared mechanical natural frequency, revealing regardless of whether the two generators are identical or not, there always exists a common-mode and an anti-mode under their common natural frequency, and the phase relationship of the speed signals of the generators depends on the extent to which the anti-mode is stimulated. The paper further demonstrates that to guarantee the effectiveness of SSDC, the anti-phase mode component of its input signal should be eliminated. Based on the above analysis, the paper introduces the design process of SSDC for multi-generator systems and verifies its effectiveness through simulation in Power Systems Computer Aided Design/Electromagnetic Transients including Direct Current (PSCAD/EMTDC.

      In the present study, a new solar-based multigeneration system integrated with an ammonia fuel cell and solid oxide fuel cell-gas turbine combined cycle to produce electricity, hydrogen, cooling and hot water is developed for analysis and performance assessment. In this regard, thermodynamic analyses and modeling through both energy and exergy approaches are employed to assess and evaluate the overall system performance. Various parametric studies are conducted to study the effects of varying system parameters and operating conditions on the energy and exergy efficiencies. The results of this study show that the overall multigeneration system energy efficiency is obtained as 39.1% while the overall system exergy efficiency is calculated as 38.7%, respectively. The performance of this multigeneration system results in an increase of 19.3% in energy efficiency as compared to single generation system. Furthermore, the exergy efficiency of the multigeneration system is 17.8% higher than the single generation system. Moreover, both energy and exergy efficiencies of the solid oxide fuel cell-gas turbine combined cycle are determined as 68.5% and 55.9% respectively.

      Availability of high-density single nucleotide polymorphism (SNP) genotyping platforms provided unprecedented opportunities to enhance breeding programmes in livestock, poultry and plant species, and to better understand the genetic basis of complex traits. Using this genomic information, genomic breeding values (GEBVs), which are more accurate than conventional breeding values. The superiority of genomic selection is possible only when high-density SNP panels are used to track genes and QTLs affecting the trait. Unfortunately, even with the continuous decrease in genotyping costs, only a small fraction of the population has been genotyped with these high-density panels. It is often the case that a larger portion of the population is genotyped with low-density and low-cost SNP panels and then imputed to a higher density. Accuracy of SNP genotype imputation tends to be high when minimum requirements are met. Nevertheless, a certain rate of genotype imputation errors is unavoidable. Thus, it is reasonable to assume that the accuracy of GEBVs will be affected by imputation errors; especially, their cumulative effects over time. To evaluate the impact of multi-generational selection on the accuracy of SNP genotypes imputation and the reliability of resulting GEBVs, a simulation was carried out under varying updating of the reference population, distance between the reference and testing sets, and the approach used for the estimation of GEBVs. Using fixed reference populations, imputation accuracy decayed by about 0.5% per generation. In fact, after 25 generations, the accuracy was only 7% lower than the first generation. When the reference population was updated by either 1% or 5% of the top animals in the previous generations, decay of imputation accuracy was substantially reduced. These results indicate that low-density panels are useful, especially when the generational interval between reference and testing population is small. As the generational interval

      Atmospheric carbon dioxide (CO 2 ) directly determines the rate of plant photosynthesis and indirectly effects plant productivity and fitness and may therefore act as a selective pressure driving evolution, but evidence to support this contention is sparse. Using Plantago lanceolata L. seed collected from a naturally high CO 2 spring and adjacent ambient CO 2 control site, we investigated multigenerational response to future, elevated atmospheric CO 2 . Plants were grown in either ambient or elevated CO 2 (700 μmol mol -1 ), enabling for the first time, characterization of the functional and population genomics of plant acclimation and adaptation to elevated CO 2 . This revealed that spring and control plants differed significantly in phenotypic plasticity for traits underpinning fitness including above-ground biomass, leaf size, epidermal cell size and number and stomatal density and index. Gene expression responses to elevated CO 2 (acclimation) were modest [33-131 genes differentially expressed (DE)], whilst those between control and spring plants (adaptation) were considerably larger (689-853 DE genes). In contrast, population genomic analysis showed that genetic differentiation between spring and control plants was close to zero, with no fixed differences, suggesting that plants are adapted to their native CO 2 environment at the level of gene expression. An unusual phenotype of increased stomatal index in spring but not control plants in elevated CO 2 correlated with altered expression of stomatal patterning genes between spring and control plants for three loci (YODA, CDKB1;1 and SCRM2) and between ambient and elevated CO 2 for four loci (ER, YODA, MYB88 and BCA1). We propose that the two positive regulators of stomatal number (SCRM2) and CDKB1;1 when upregulated act as key controllers of stomatal adaptation to elevated CO 2 .

      Multi-generational oxidation of volatile organic compound (VOC) oxidation products can significantly alter the mass, chemical composition and properties of secondary organic aerosol (SOA) compared to calculations that consider only the first few generations of oxidation reactions. However, the most commonly used state-of-the-science schemes in 3-D regional or global models that account for multi-generational oxidation (1) consider only functionalization reactions but do not consider fragmentation reactions, (2) have not been constrained to experimental data and (3) are added on top of existing parameterizations. The incomplete description of multi-generational oxidation in these models has the potential to bias source apportionment and control calculations for SOA. In this work, we used the statistical oxidation model (SOM) of Cappa and Wilson (2012), constrained by experimental laboratory chamber data, to evaluate the regional implications of multi-generational oxidation considering both functionalization and fragmentation reactions. SOM was implemented into the regional University of California at Davis / California Institute of Technology (UCD/CIT) air quality model and applied to air quality episodes in California and the eastern USA. The mass, composition and properties of SOA predicted using SOM were compared to SOA predictions generated by a traditional two-product model to fully investigate the impact of explicit and self-consistent accounting of multi-generational oxidation.Results show that SOA mass concentrations predicted by the UCD/CIT-SOM model are very similar to those predicted by a two-product model when both models use parameters that are derived from the same chamber data. Since the two-product model does not explicitly resolve multi-generational oxidation reactions, this finding suggests that the chamber data used to parameterize the models captures the majority of the SOA mass formation from multi-generational oxidation under the conditions

      This paper develops a new Organic Rankine Cycle (ORC) based multigenerational system to meet the demands of a net zero energy building and assesses such a system for an application to a net zero energy house in Lebanon. Solar energy is the prime source for the integrated system to achieve multigeneration to supply electricity, fresh and hot water, seasonal heating and cooling. The study starts by optimizing the power system with and without grid connection. Then, a comprehensive thermodynamic analysis through energy and exergy, and a parametric study to assess the sensitivity and improvements of the overall system are conducted. Furthermore, exergoeconomic analysis and a follow-up optimization study for optimizing the total system cost to the overall system efficiency using genetic algorithm to obtain the optimal design or a set of optimal designs (Pareto Front), are carried out. The present results show that the optimum solar energy system for a total connected load to the house of 90 kWh/day using a combination of ORC, batteries, convertor has a total net present cost of US $52,505.00 (based on the prices in 2013) with a renewable energy fraction of 1. Moreover, the optimization for the same connected load with ORC, batteries and converter configuration with grid connection results in a total net present cost of $50,868.00 (2013) with a renewable energy fraction of 0.992 with 169 kg/yr of CO 2 emissions. In addition, exergoeconomic analysis of the overall system yields a cost of $117,700.00 (2013), and the multi-objective optimization provides the overall exergetic efficiency by 14% at a total system cost increase of $10,500.00 (2013). - Highlights: • To develop a new Organic Rankine Cycle (ORC) based multigenerational system to meet the demands of a net zero energy building. • To perform a comprehensive thermodynamic analysis through energy and exergy approaches. • To apply an exergoeconomic model for exergy-based cost accounting. • To undertake

      For the first time, we demonstrate that tungsten (W) nanoparticles (NPs) are created when a tungsten target is exposed to low-pressure, high density hydrogen plasma. The plasma was generated using a novel dual plasma system combining a microwave discharge and a pulsed direct-current (DC) discharge. The tungsten surface originates in the multi-generational formation of a significant population of 30-70 nm diameter particles when the W cathode is biased at ~  -1 kV and submitted to ~1020 m2 s-1 H+/H2+ /H3+ ions flux. The evidenced NPs formation should be taking into account as one of the consequence of the plasma surface interaction outcomes, especially for fusion applications.

    16. Synergy effects of fluoxetine and variability in temperature lead to proportionally greater fitness costs in Daphnia: A multigenerational test.

      Increased variability in water temperature is predicted to impose disproportionally greater fitness costs than mean increase in temperature. Additionally, water contaminants are currently a major source of human-induced stress likely to produce fitness costs. Global change models forecast an increase in these two human-induced stressors. Yet, in spite the growing interest in understanding how organisms respond to global change, the joint fitness effects of water pollution and increased variability in temperature remain unclear. Here, using a multigenerational design, we test the hypothesis that exposure to high concentrations of fluoxetine, a human medicine commonly found in freshwater systems, causes increased lifetime fitness costs, when associated with increased variability in temperature. Although fluoxetine and variability in temperature elicited some fitness cost when tested alone, when both stressors acted together the costs were disproportionally greater. The combined effect of fluoxetine and variability in temperature led to a reduction of 37% in lifetime reproductive success and a 17.9% decrease in population growth rate. Interestingly, fluoxetine and variability in temperature had no effect on the probability of survival. Freshwater systems are among the most imperilled ecosystems, often exposed to multiple human-induced stressors. Our results indicate that organisms face greater fitness risk when exposed to multiple stressors at the same time than when each stress acts alone. Our study highlights the importance of using a multi-generational approach to fully understand individual environmental tolerance and its responses to a global change scenario in aquatic systems.

      In order to understand how bisphenol A (BPA) exposure acts on the evolutionary dynamics of populations and changes of stress response across generations, the model animal Caenorhabditis elegans was used to conduct the multigenerational testing. Multiple endpoints at the physiological (growth, reproduction, and locomotion behaviors) and molecular (stress-related gene expressions) levels were examined by multigenerational exposure to low-concentration BPA (0.001–10 μM) across four generations. The results showed that changes of physiological-level effects across four generations varied in magnitude and direction, depending on the exposure concentrations. C. elegans individuals in the first generation grew smaller, moved slower, and produced less offsprings than the controls by BPA exposure. As for each trait tested, the first generation response could be commonly mirrored in the subsequent generations at the highest concentration of 10 μM. However, at lower concentrations, response of parental generation was a relatively poor predictor of the effects on progeny, as acclimation or cumulative damage could occur in the subsequent generations. The integrated gene expression profiles visually illustrated that the tested gene expressions at low concentrations (0.001–0.01 μM) were more obviously changed in both G_1 and G_4 generations, and the G_1 generation showed a much greater degree of increase in stress-related gene expressions than the G_4 generation. The multigenerational toxicity data emphasize the need of considering biological effects over multiple generations to conduct accurate assessment of environmental risks of toxicants on population dynamics. - Highlights: • Multigenerational exposure was conducted to evaluate effects of BPA on C. elegans. • Changes of biological effects varied in magnitude and direction across generations. • A more significant induction in stress-related gene expressions was found in G_1. • Multigenerational tests have

      1991-04-01

      This work briefly describes Brazilian colonization of the Paraguayan agricultural frontier, analyzes factors responsible for expelling population from Brazil and for attracting Brazilians to Paraguay, and assesses the economic and social consequences of immigration to the area. Paraguay's vast and sparsely populated agricultural frontier in areas outside the Central subregion underwent a process of intense colonization from the early 1960s to the mid-1980s. The Paraguayan government initiated an ambitious colonization program in 1963 to increase production, relieve population pressure and subdivision of small parcels in the Central subregion, encourage agricultural modernization, and produce a more diversified agriculture. Paraguayan agriculture in the early 1960s suffered from excessive concentration of land in a few hands and resulting exclusion of around 3/4 of workers from ownership and from any possibility of obtaining credit to fund technological improvements. Results of studies 2 decades after implementation of the colonization plan suggest that it has failed in significant areas. Although a considerable population redistribution alleviated pressure in the Central subregion, it apparently resulted more from spontaneous movement of peasants outside the colonization areas than from the official program. Concentration of lands is now occurring in the colonization area. Assistance for agricultural modernization and diversification of production in the peasant sector has been minimal. On the other hand, production of soy, wheat, and cotton for export increased substantially, because of an entrepreneurial agriculture capitalized by foreign as well as national interests The unmet goals of the colonization program would have required structural reforms rather than simple spatial redistribution of the population. Many of the colonists in the 1970s were Brazilian families displaced by mechanized agriculture in the southern states of Parana, Santa Catarina, and Rio

      The Brazilian Twin Registry (BTR) was established in 2013 and has impelled twin research in South America. The main aim of the initiative was to create a resource that would be accessible to the Brazilian scientific community as well as international researchers interested in the investigation of the contribution of genetic and environmental factors in the development of common diseases, phenotypes, and human behavior traits. The BTR is a joint effort between academic and governmental institutions from Brazil and Australia. The collaboration includes the Federal University of Minas Gerais (UFMG) in Brazil, the University of Sydney and University of Melbourne in Australia, the Australian Twin Registry, as well as the research foundations CNPq and CAPES in Brazil. The BTR is a member of the International Network of Twin Registries. Recruitment strategies used to register twins have been through participation in a longitudinal study investigating genetic and environmental factors for low back pain occurrence, and from a variety of sources including media campaigns and social networking. Currently, 291 twins are registered in the BTR, with data on demographics, zygosity, anthropometrics, and health history having been collected from 151 twins using a standardized self-reported questionnaire. Future BTR plans include the registration of thousands of Brazilian twins identified from different sources and collaborate nationally and internationally with other research groups interested on twin studies.

      2011-02-01

      Full Text Available A content analysis of four Brazilian news media portals found that economic news dominated the top headlines with little attention paid to education, the environment and welfare. Other trends included a focus on local events and national news sources, reliance on few sources, mostly official ones, and a low percentage of news that fitted the concept of newsworthiness (a combination of both social significance and deviance concepts. Other findings of a study of 432 top news stories published by UOL, Estadão, iG and Terra during a 15-day period between February and March 2008 indicate that the top portions of the portals’ front pages carry news that lacks story depth, editorial branding, and multimedia applications. The results suggest that online news portals are in their infancy although Brazil has the largest online population of Latin America. This study hopes to shed light on the gatekeeping process in Brazilian news portals. Brazilian media portals have yet to become a significant editorial force able to provide knowledge about social issues and public affairs in a socially responsible fashione.

      Full Text Available Research was carried out in 2006 in three gminas (administrative boroughs of the Małopolska Province – Dębno, Wieliczka, and Zabierzów. 40 multigeneration rural families were selected in each gmina. Interviews were conducted with them on the basis of a questionnaire made up of three parts focused on the representatives of three genera-tions: grandparents, parents, and grandchildren. 360 people were surveyed in total. The results of the research, which are presented here, will try to provide an answer to the ques-tion of how critical a role tradition plays in the life of multigeneration rural families, and also to what extent they cherish the customs and habits which they have inherited from previous generations.

    7. The Corporate Governance of Privately Controlled Brazilian Firms

      Directory of Open Access Journals (Sweden)

      2009-09-01

      Full Text Available We provide an overview of the corporate governance practices of Brazilian public companies, based primarily on an extensive 2005 survey of 116 companies. We focus on the 88 responding Brazilian private firms which are not majority owned by the state or a foreign company. We identify areas where Brazilian corporate governance is relatively strong and weak. Board independence is an area of weakness: The boards of most Brazilian private firms are comprised entirely or almost entirely of insiders or representatives of the controlling family or group. Many firms have zero independent directors. At the same time, minority shareholders have legal rights to representation on the boards of many firms, and this representation is reasonably common. Financial disclosure lags behind world standards. Only a minority of firms provide a statement of cash flows or consolidated financial statements. However, many provide English language financial statements, and an English language version of their website. Audit committees are uncommon, but many Brazilian firms use an alternate approach to ensuring financial statement accuracy – establishing a fiscal board. A minority of firms provide takeout rights to minority shareholders on a sale of control. Controlling shareholders often use shareholders agreements to ensure control.

      The purpose of this work was to obtain a broad knowledge of the circumstances under which activities involving ionizing radiations are held at brazilian academic institutions. Around 90 institutions (universities and isolated schools of both public and private sectors) were invited, by mail, to answer an inquiry with questions from technical to legal aspects of their activities with radiations. Information received from 2/3 of institutions contacted, permitted conclusions as: there is a wide ignorance about radioprotection procedures and legislation, although few universities maintain some efficient radioprotection staff; there is a need for the establishment of a standard radioprotection text dedicated to those specific activities of the sector.

      Ana Luiza Albuquerque Cruz

      2014-08-01

      Full Text Available In the context of a family owned company, the general literature recognizes that the interaction between the family and the company is one of the main constituting and influential dimensions of the dynamics within these organizations in regards to the succession process. The main objective is to analyze the process of socialization between members of a business family and their influence in the dynamic constitution of the succession process. For such, a qualitative approach was adopted based on the technique of case study, conducted in a company in the pharmaceutical and retail sector with more than 100 years of operations in Belo Horizonte. From the interviews conducted with the researched subjects it was possible to observe that the early insertion of the successor-heir in the company dynamics allowed for him to be projected as the guardian of the family values, bearer of externally recognized competencies, depositary of the legacy and responsible for the continuity of the family. All of these capacities have contributed to legitimize the heir-successors in the process of succession of the researched company.

      To determine the influence of reproductive history on the prevalence of obesity in Brazilian women and the possible modifying effect of socioeconomic variables on the association between parity and excess weight. A retrospective analysis of complex sample data collected as part of the 2006 Brazilian National Survey on Demography and Health, which included a group representative of women of childbearing age in Brazil was conducted. The study included 11 961 women aged 20 to 49 years. The association between the study factor (parity) and the outcome of interest (obesity) was tested using logistic regression analysis. The adjusted effect of parity on obesity was assessed in a multiple regression model containing control variables: age, family purchasing power, as defined by the Brazilian Association of Research Enterprises (ABEP), schooling, and health care. Significance level was set at below 0.05. The prevalence of obesity in the study population was 18.6%. The effect of parity on obesity was significant (P for trend parity and age. Family purchase power had a significant odds ratio for obesity only in the unadjusted analysis. In the adjusted model, this variable did not explain obesity. The present findings suggest that parity has an influence on obesity in Brazilian women of childbearing age, with higher prevalence in women vs. without children.

      Life expectancy (LE) refers to the number of years that an individual is expected to survive. Emphasis is frequently placed on the relationship between LE and the conditions under which a population lives, but fewer studies have investigated the relationship between stress factors associated with specific professions and their effects on LE. The aim of this study is to evaluate Brazilian neurosurgeons' life expectancies (BNLEs) and compare them with those of physicians (both Brazilian and foreign) from other fields, as well as with Brazilian nondoctors. The Brazilian Society of Neurosurgery death registry was used to obtain data that compared LEs from non-neurosurgeon physicians, as described in the national and international literature. BNLEs were also compared with the LEs of Brazilian citizens. Fifty-one neurosurgeons died between 2009 and 2016. All were males. The mean age at death was 68.31 ± 17.71 years. Among all-cause mortality, the breakdown was 20% cardiovascular diseases, 39% malignancies, 10% external factors, 6% gastrointestinal disorders, 12% neurologic illnesses, and 14% unknown causes. BNLE was shorter than LE of male Brazilian citizens. LE was similar among neurosurgeons and other doctors but shorter compared with Brazilian citizens. Further research is needed to provide data that can add to and confirm these results. Copyright © 2018 Elsevier Inc. All rights reserved.

      An 8-year-old girl born to a family with more than three generations of dominant dystrophic epidermolysis bullosa (DDEB) presented with life-threatening confluent skin erosions, mitten hand deformity, and failure to thrive. Reassessment of her family history and genetic testing showed compound heterozygous COL7A mutations, one inherited from her DDEB-affected mother and one from her unaffected, healthy father. This family illustrates the risk of unexpected, severe, autosomal recessive epidermolysis bullosa (EB) in a family with milder, multigenerational autosomal dominant EB. Clinicians should recognize the clinical spectrum of dystrophic EB and recommend genetic consultation when the phenotype conflicts with family history. © 2017 Wiley Periodicals, Inc.

      Full Text Available Brazil is the 5th largest country in the world and its present population, in excess of 190 million, is highly heterogeneous, as a result of centuries of admixture between Amerindians, Europeans and Sub-Saharan Africans. The estimated individual proportions of biogeographical ancestry vary widely and continuously among Brazilians, most individuals - irrespective of self-identification as White, Brown or Black, the major categories of the Brazilian Census race/color system - having significant degrees of European and African ancestry, while a sizeable number display also Amerindian ancestry. These features have important pharmacogenetic (PGx implications: first, extrapolation of PGx data from relatively well-defined ethnic groups is clearly not applicable to the majority of Brazilians; second, the frequency distribution of polymorphisms in pharmacogenes (e.g. CYP3A5, CYP2C9, GSTM1, ABCB1, GSTM3, VKORC, etc varies continuously among Brazilians and is not captured by race/color self-identification; third, the intrinsic heterogeneity of the Brazilian population must be acknowledged in the design and interpretation of PGx studies in order to avoid spurious conclusions based on improper matching of study cohorts. The peculiarities of PGx in Brazilians are illustrated with data for different therapeutic groups, such as anticoagulants, HIV-protease inhibitors and nonsteroidal antinflammatory drugs, and the challenges and advantages created by population admixture for the study and implementation of PGx are discussed. PGx data for Amerindian groups and Brazilian-born, first generation Japanese are presented to illustrate the rich diversity of the Brazilian population. Finally, I introduce the reader to the Brazilian Pharmacogenetic Network or Refargen (www.refargen.org.br, a nationwide consortium of research groups, with the mission to provide leadership in PGx research and education in Brazil, with a population health impact.

Consequently, we reared a marine polychaete, Ophryotrocha labronica , previously cultured for approximately 33 generations under a low/variable pH regime, under elevated and low p CO 2 for six generations. The strain used was found to be tolerant to elevated p CO 2 conditions. In generations F1 and F2 females' fecundity was significantly lower in the low p CO 2 treatment. However, from generation F3 onwards there were no differences between p CO 2 treatments, indicating that trans-generational effects enabled the restoration and maintenance of reproductive output. Whilst the initial fitness recovery was likely driven by trans-generational plasticity (TGP), the results from reciprocal transplant assays, performed using F7 individuals, made it difficult to disentangle between whether TGP had persisted across multiple generations, or if evolutionary adaptation had occurred. Nonetheless, both are important mechanisms for persistence under climate change. Overall, our study highlights the importance of multi-generational experiments in more accurately determining marine metazoans' responses to changes in p CO 2 , and strengthens the case for exploring their use in conservation, by creating specific p CO 2 tolerant strains of keystone ecosystem species.

      We investigated the effects of genotype (two different clones) and multigenerational Cd-exposure history on Cd toxicity, individual fitness, and biokinetics in populations of a freshwater cladoceran Daphnia magna. The adults of the tolerant (T) clone had longer mean-survival-time than the sensitive (S) clone in both control groups (without Cd-exposure) and continuous Cd-exposure groups, but the two clones showed comparable resistances to acute Cd stress in the recovery groups. The body concentration of metallothionein (MT) played a critical role in handling Cd stress, which mainly accounted for the significant difference between the two clones in terms of survival distribution. High comparability of these two clones in individual fitness parameters and biokinetics suggested that these parameters are unlikely driven by genetic variation. For each specific clone, continuous Cd-exposure inhibited the animal growth, elevated the MT induction, and increased the Cd uptake rate (ingestion rate, assimilation efficiency from dietary phase, and uptake rate from dissolved phase), all of which enhanced the weight-specific Cd accumulation in daphnids' bodies. The strong dependence of biokinetic parameters on environmental factors (e.g., food concentrations, pH, dissolved or dietary metal concentration, and metal exposure histories) rather than on genotypes implied the great potential of using biokinetics in inter-lab comparisons and environmental risk assessments.

      High-fluoride (100 and 200 ppm) water was administered to rats orally to study the fluoride-induced changes on the thyroid hormone status, the histopathology of discrete brain regions, the acetylcholine esterase activity, and the learning and memory abilities in multigeneration rats. Significant decrease in the serum-free thyroxine (FT4) and free triiodothyronine (FT3) levels and decrease in acetylcholine esterase activity in fluoride-treated group were observed. Presence of eosinophilic Purkinje cells, degenerating neurons, decreased granular cells, and vacuolations were noted in discrete brain regions of the fluoride-treated group. In the T-maze experiments, the fluoride-treated group showed poor acquisition and retention and higher latency when compared with the control. The alterations were more profound in the third generation when compared with the first- and second-generation fluoride-treated group. Changes in the thyroid hormone levels in the present study might have imbalanced the oxidant/antioxidant system, which further led to a reduction in learning memory ability. Hence, presence of generational or cumulative effects of fluoride on the development of the offspring when it is ingested continuously through multiple generations is evident from the present study.

      Multigenerational co-residence is a widespread phenomenon in China but there is little knowledge about the impact of power dynamics on smoking behaviors among extended family residents. Using a gender lens, this ethnographic study explored how young mothers in extended families in mainland China managed the smoking of their husbands and other family members. Analysis of data resulted in a model of 'two units-three domains' to reflect gendered relationships between young mothers and other family members, and young mothers' participation in family management. Exploration of the mothers' efforts to deal with household smoking using the model provided an explanation for why the young mothers had limited control over household space and could only impose partial restrictions on home smoking in the extended family.

      Work-family conflict and time scarcity may affect health. We investigated the association between these issues and migraine, taking into account job strain. Baseline data from ELSA-Brasil (6,183 women; 5,664 men) included four indicators of work-family conflict: time- and strain-based interference of work with family (TB-WFC, SB-WFC), interference of family with work (FWC) and lack of time for personal care and leisure (LOT). Migraine was classified according to International Headache Society criteria. Among women, definite migraine was associated with SB-WFC (odds ratio [OR] = 1.28; 95% confidence interval [CI] 1.06-1.55), FWC (OR = 1.32; 1.00-1.75), and LOT (OR = 1.30; 1.08-1.58). Probable migraine was associated with SB-WFC (OR = 1.17; 1.00-1.36). High psychological job demands and low social support interacted with LOT in association with definite migraine. Among men, probable migraine was associated with LOT (OR = 1.34; 1.09-1.64), and there were interactions between job strain and WFC for probable migraine. Balancing the demands of professional and domestic spheres could be highly relevant in the management of migraines. Am. J. Ind.

      The scope of this article is to assess the main characteristics of the traditions and experiences of empowerment of users and family members in mental health treatment and services in Anglo-Saxon countries and in Brazil and the repercussions and strategies thereof in the field of evaluative and interventional research in mental health. Based on a brief bibliographical review of the literature, the aim is to compare how the empowerment tradition has developed in the two realities, based on the characteristics of the economic, political, social - and especially cultural - context. The review revealed how these contexts induce different perspectives on how to foster the autonomy and empowerment of users and family members in social policies and mental health, as well as their appropriation in the field of evaluative and interventional research. In Anglo-Saxon countries, this tradition has been vigorously promoted over the past four decades, and in Brazil the participative strategies emphasize mixed mechanisms - professionals, users and family members together - with the dominant presence of the professionals. The strategies in Brazil more directly designed for users and family members are recent and have been implemented from 2005 onwards.

      Obesity prevalence in the Brazilian adult population is 12.5% among men and 16.9% among women. Obesity control has been a subject of concern in Brazilian health policies since the publication of the National Food and Nutrition Policy in 1999. The initiatives include a comprehensive national intersectorial plan for obesity prevention and control focused on confronting its social and environmental causes, development of a food and nutrition education framework aimed at intersectorial public policies in the food and nutritional security field, promotion and provision of healthy food in school environments (linked to family farming), structuring nutrition actions in primary healthcare in the national healthcare system, promoting community physical activity, food regulation and control, and encouragement of public participation and food control. We conclude that several initiatives have been developed in Brazil to deal with the challenge of implementing an intergovernmental, intersectorial response to reverse the rising overweight and obesity rates. The success of this response will depend on a governance model that promotes joint and integrated action by different sectors and active participation of society to consolidate the actions, places and laws that protect health and promote healthy lifestyles. © 2013 The Authors.

      The multigenerational survival rate for family-owned businesses is not good. Lack of a shared vision for the family enterprise and weak next-generation leadership are often cited as two of the leading reasons for the failure of family firms to successfully transition from one generation of family ownership to the next. The climate of the business-owning family has also been suggested as important to the performance of the family enterprise. Despite these commonly held tenets, there is a lack of rigorous quantitative research that explores the relationships among these three factors. To address this gap, a quantitative study of 100 next-generation family firm leaders and 350 family and non-family leaders and employees with whom they work was conducted. The results demonstrate that a shared vision for the family business has a strong effect on the leadership effectiveness of next-generation family leaders and a moderate effect on the degree to which they are positively engaged with their work. The findings also show that two dimensions of family climate significantly influence the likelihood that a shared vision for the family firm has been created. Open communication in the family is positively related to the presence of a shared vision for the business. Intergenerational authority, which refers to a senior generation that exercises unquestioned authority and sets the rules, is negatively related to the presence of a shared vision. Surprisingly, a third dimension of family climate, cognitive cohesion, which includes shared values in the family, had no relationship with the degree to which there was a shared vision for the family business. The implications for family business owners is that they would be wise to spend as much time on fostering a positive family climate characterized by open communication as they do on creating and executing a successful business strategy if their goal is to pass the business from one generation of family owners to the next.

      To test the hypothesis that disordered eating in second- and third-generation women would be related to their levels of Holocaust exposure and family dysfunction. One hundred eight mother-daughter dyads were ascertained through the daughters, all Israeli college students 18-35 years of age. Mothers and daughters assessed themselves on family function, Holocaust exposure and disordered eating. The disordered eating of women of the third generation was partially predicted by their mothers' disordered eating and by their mothers' Holocaust exposure. The second generation reported more maternal over-protection and emotional over-involvement than did the third generation. Contrary to expectation, the third-generation women were more Holocaust exposed than were the second generation. The nature of Holocaust exposure for second and third generations needs further study and clarification in relation to disordered eating. There is considerable disparity between the results of clinical and qualitative studies which tend to find a strong relationship between Holocaust exposure and psychopathology, and population-based quantitative studies which tend to find a much weaker relationship. 2006 John Wiley & Sons, Ltd and Eating Disorders Association

      Support for authoritarian approaches to parenting, including corporal punishment, is known to be elevated among individuals with low current levels of socioeconomic attainment. The objectives of this study are: (1) to determine whether authoritarian parenting dispositions are related to disadvantages in one's social background, in addition to one's present socioeconomic standing; and (2) to distinguish, in this regard, between support for spanking and other authoritarian parenting dispositions. Ordered logit models, applied to General Social Survey data concerning a nationally representative sample of US adults, are used to examine relationships of authoritarian parenting dispositions to the socioeconomic positions that respondents currently occupy and in which they were raised. It is found that support for spanking (N=10,725) and valuing of obedience (N=10,043) are inversely related to the socioeconomic status (SES) of one's family of origin, and that these associations are robust to controls for one's current SES. A disadvantaged family background is found to increase support for spanking most among those with high current SES. Strong associations (robust to controls for SES indicators) are additionally found between African-American racial identity and support for authoritarian parenting. Prior research indicates that authoritarian parenting practices such as spanking may be harmful to children. Thus, if the parenting attitudes analyzed here translate into parenting practices, then this study's findings may point to a mechanism for the intergenerational transmission of disadvantages.

      Full Text Available The diamondback moth (DBM, Plutella xylostella (L. (Lepidoptera: Plutellidae, is a major pest of Brassicaceae family in Iran. This study investigated the sublethal effects of pyriproxyfen, a juvenile hormone analogue, on DBM, for two subsequent generations. The leaf dip bioassay method was adopted in conducting this experiment. Sublethal concentrations resulted in a significant decrease in fecundity, oviposition period, and pupal weight of parents and offspring generations. Also, the development time of DBM was prolonged after exposure to pyriproxyfen. The biological parameters such as net reproductive rate (R0 and intrinsic (rm and finite (λ rate of increase were lower than control in treatment groups, significantly. From our investigations, pyriproxyfen is a good choice for control of the diamondback moth population through continuous generations.

      Full Text Available Xeroderma pigmentosum (XP is a rare autosomal recessive disorder characterized by DNA repair defects that cause photophobia, sunlight-induced cancers, and neurodegeneration. Prevalence of germline mutations in the nucleotide excision repair gene XPA vary significantly in different populations. No Brazilian patients have been reported to carry a germline mutation in this gene. In this study, the germline mutational status of XPA was determined in Brazilian patients exhibiting major clinical features of XP syndrome. The study was conducted on 27 unrelated patients from select Brazilian families. A biallelic inactivating transition mutation c.619C>T (p.Arg207Ter was identified in only one patient with a history of neurological impairment and mild skin abnormalities. These findings suggest that XP syndrome is rarely associated with inherited disease-causing XPA mutations in the Brazilian population. Additionally, this report demonstrates the effectiveness of genotype-phenotype correlation as a valuable tool to guide direct genetic screening.

      Multiple avenues of research (e.g., criminal careers, intergenerational family transmission, and epidemiological studies) have indicated a concentration of antisocial traits and behaviors that cluster among families and within individuals in a population. The current study draws on each of these perspectives in exploring the intergenerational contours of antisocial personality disorder across multiple generations of a large-scale epidemiological sample. The analytic sample of persons meeting criteria for antisocial personality disorder (N = 1,226) was derived from waves I and II of the National Epidemiologic Survey on Alcohol and Related Conditions. Path analytic, latent class, and multinomial models were executed to describe and elucidate family histories among persons diagnosed with antisocial personality disorder. Three classes of an antisocial family tree were found: minimal family history of problem behaviors (70.3 % of sample) who were characterized by higher socioeconomic functioning, parental and progeny behavior problems (9.4 % of sample) who were characterized by criminal behaviors, psychopathology, and substance use disorders, and multigenerational history of problem behaviors (20.3 % of sample) who were characterized by alcoholism, psychopathology, and versatile criminal offending. These findings add a typology to intergenerational studies of antisocial behavior that can assist in identifying etiological and treatment factors among those for whom crime runs in the family.

      Full Text Available CONTEXT: CHEK2 encodes a cell cycle checkpoint kinase that plays an important role in the DNA damage repair pathway, activated mainly by ATM (Ataxia Telangiectasia Mutated in response to double-stranded DNA breaks. A germline mutation in CHEK2, 1100delC, has been described as a low penetrance allele in a significant number of families with breast and colorectal cancer in certain countries and is also associated with increased risk of contralateral breast cancer in women previously affected by the disease. About 5%-10% of all breast and colorectal cancers are associated with hereditary predisposition and its recognition is of great importance for genetic counseling and cancer risk management. OBJECTIVES: Here, we have assessed the frequency of the CHEK2 1100delC mutation in the germline of 59 unrelated Brazilian individuals with clinical criteria for the hereditary breast and colorectal cancer syndrome. METHODS: A long-range PCR strategy followed by gene sequencing was used. RESULTS: The 1100delC mutation was encountered in the germline of one (1.7% individual in this high risk cohort. This indicates that the CHEK2 1100delC is not commonly encountered in Brazilian families with multiple diagnoses of breast and colorectal cancer. CONCLUSION: These results should be confirmed in a larger series of families and further testing should be undertaken to investigate the molecular mechanisms underlying the hereditary breast and colorectal cancer phenotype.INTRODUÇÃO: CHEK2 codifica uma proteína quinase envolvida em um ponto de checagem do ciclo celular que desempenha um papel importante na via de reparação do DNA, danos ativados principalmente por ATM (Ataxia Telangiectasia Mutado em resposta a danos na dupla hélice do DNA.

      2017-06-01

      Full Text Available The FUT2 gene encodes an α-1,2-fucosyltransferase responsible for the expression of ABO histo-blood-group antigens on mucosal surfaces and bodily secretions. Individuals who carry at least one functional allele are known as “secretors,” whereas those homozygous for loss-of-function mutations are known as “non-secretors.” Non-secretor individuals are more susceptible to chronic inflammatory disorders such as Crohn’s Disease, which may be mediated by alterations in the microbiota. Here, we investigated the dynamics of microbial community assembly with respect to genotype using a Fut2-deficient mouse model, taking the genotype of the maternal lineage over two generations into account. We found strong differences in community assembly of microbial communities over time, depending on the Fut2 genotype of the host and that of their progenitors. By applying network analyses, we further identified patterns of specialization and stabilization over time, which are influenced by the host and parental genotype during the process of community development. We also show genotype- and breeding-dependent patterns of community susceptibility to disturbance in a novel in silico approach integrating ecological- and network analysis. Our results indicate that it may be important to investigate the influence of Fut2 genotype in a familial context in order to fully understand its role in the etiology of chronic inflammatory disorders.

      To assess intergenerational associations between dental caries and nutritional status, oral hygiene habits, and diet. A cross-sectional study was conducted with three generations of 54 families. Inclusion criteria were senior citizens with an adult son/daughter who also had a child (five to 12 years old). Dental caries was assessed using the decayed, missing, filled, primary teeth (dmft) and permanent teeth (DMFT) indexes. Nutritional status was evaluated using the body mass index (BMI), waist circumference, and percentage of body fat. Dietary habits, oral hygiene habits, and socioeconomic status were evaluated using a structured questionnaire. Children/adolescents with higher BMI had a lower dmft/DMFT index, and those who never or almost never consumed fruits and vegetables as snacks had a higher dmft/ DMFT index. When parents did not visit the dentist regularly, children/adolescents had more teeth affected by dental caries. When parents consumed sugar two or more times between meals, the number of affected teeth in children/adolescents increased. When children/ adolescents had a higher body mass index and they consumed fruits/vegetables as snacks more frequently, their caries experiences were lower. When their parents' did not visit the dentist regularly and they consumed sugar between meals more frequently, the children's caries experiences were higher.

      Background Length of residence in the United States (US), changes in dietary and physical activity behaviors, and economic and social barriers contribute to high childhood obesity rates among children from immigrant families in the US. Brazilians comprise a fast-growing immigrant population group in the US, yet little research has focused on health issues affecting Brazilian children in immigrant families. Understanding sociocultural and environmental influences on parents' beliefs and practices related to child feeding and weight status is essential to altering obesity trends in this group. Methods Qualitative study consisting of five focus groups with a convenience sample of 29 Brazilian immigrant mothers. Results Analyses revealed that the sociocultural and environment transitions faced by Brazilian immigrant mothers' influence their beliefs and practices related to child feeding and weight status. Additionally, acculturation emerged as a factor affecting mothers' feeding practices and their children's eating habits, with mothers preferring Brazilian food environments and that their children preferring American food environments. Mothers viewed themselves as being responsible for promoting and maintaining their children's healthy eating and feeding behaviors, but changes in their social and cultural environments due to immigration and the pressures and demands of raising a family in a new country make this difficult. Conclusions Health promotion interventions to improve healthful eating and feeding practices of Brazilian children in immigrant families must account for social and cultural changes and daily life demands due to immigration as well as potential variation in the levels of acculturation between mothers and their children.

      Full Text Available Neste artigo discutimos as mudanças representadas pela entrada de mulheres no trabalho fabril numa região de industrialização recente, buscando verificar em que medida essa inserção, em um contexto de crise do emprego e em uma região marcada pela informalidade de parte significativa das atividades econômicas, tem influenciado a redefinição dos papéis familiares e acentuado conflitos geradores de violência doméstica. Foram realizadas entrevistas com 14 mulheres que denunciaram algum tipo de violência praticada por seus maridos ou companheiros na Delegacia Regional da Mulher, no município de Crato, CE. Os dados obtidos apontam, entre outros aspectos, que a entrada das mulheres na esfera pública e a autonomia financeira, propiciadas pelo trabalho fabril, tendem a provocar mudanças nos tradicionais papéis de gênero, cujas consequências tem se expressado no questionamento do lugar do homem como provedor, nos rompimentos do grupo familiar e violência doméstica contra as trabalhadoras.In this article, we will argue about the changes represented by the entrance of women in the factory work in a region of recent industrialization, aiming at verifying to which extent such insertion, in a context of employment crisis in a region marked by informal labor activities, has influenced the redefinition of the family roles and increased conflicts that cause domestic violence. A group of 14 women workers that denounced the domestic violence in Crato City, Ceará State, was observed. We intend to recoup the changes perceived by these workers in its life of work and its ordinary life. The women entrance in the public sphere tends to pressure for changes in the traditional roles of gender with distinct gradations, since adjustments in the domestic life until disruption of the family group.

      The initial aim of this multiagency, multigenerational record linkage study is to identify childhood profiles of developmental vulnerability and resilience, and to identify the determinants of these profiles. The eventual aim is to identify risk and protective factors for later childhood-onset and adolescent-onset mental health problems, and other adverse social outcomes, using subsequent waves of record linkage. The research will assist in informing the development of public policy and intervention guidelines to help prevent or mitigate adverse long-term health and social outcomes. The study comprises a population cohort of 87,026 children in the Australian State of New South Wales (NSW). The cohort was defined by entry into the first year of full-time schooling in NSW in 2009, at which time class teachers completed the Australian Early Development Census (AEDC) on each child (with 99.7% coverage in NSW). The AEDC data have been linked to the children's birth, health, school and child protection records for the period from birth to school entry, and to the health and criminal records of their parents, as well as mortality databases. Descriptive data summarising sex, geographic and socioeconomic distributions, and linkage rates for the various administrative databases are presented. Child data are summarised, and the mental health and criminal records data of the children's parents are provided. In 2015, at age 11 years, a self-report mental health survey was administered to the cohort in collaboration with government, independent and Catholic primary school sectors. A second record linkage, spanning birth to age 11 years, will be undertaken to link this survey data with the aforementioned administrative databases. This will enable a further identification of putative risk and protective factors for adverse mental health and other outcomes in adolescence, which can then be tested in subsequent record linkages.

      Full Text Available Multi-generational oxidation of volatile organic compound (VOC oxidation products can significantly alter the mass, chemical composition and properties of secondary organic aerosol (SOA compared to calculations that consider only the first few generations of oxidation reactions. However, the most commonly used state-of-the-science schemes in 3-D regional or global models that account for multi-generational oxidation (1 consider only functionalization reactions but do not consider fragmentation reactions, (2 have not been constrained to experimental data and (3 are added on top of existing parameterizations. The incomplete description of multi-generational oxidation in these models has the potential to bias source apportionment and control calculations for SOA. In this work, we used the statistical oxidation model (SOM of Cappa and Wilson (2012, constrained by experimental laboratory chamber data, to evaluate the regional implications of multi-generational oxidation considering both functionalization and fragmentation reactions. SOM was implemented into the regional University of California at Davis / California Institute of Technology (UCD/CIT air quality model and applied to air quality episodes in California and the eastern USA. The mass, composition and properties of SOA predicted using SOM were compared to SOA predictions generated by a traditional two-product model to fully investigate the impact of explicit and self-consistent accounting of multi-generational oxidation.Results show that SOA mass concentrations predicted by the UCD/CIT-SOM model are very similar to those predicted by a two-product model when both models use parameters that are derived from the same chamber data. Since the two-product model does not explicitly resolve multi-generational oxidation reactions, this finding suggests that the chamber data used to parameterize the models captures the majority of the SOA mass formation from multi-generational oxidation under

      Full Text Available The present work deals with the Brazilian exports of sawnwood of non-coniferous, veneer sheets and plywood, from 1961 to 2002. The data regarding the three studied products, sawnwood of non-coniferous, veneer sheets and plywood, were joined through the method of Fisher so that an econometric evaluation of the market of the three products could be carried out. Supply and demand models of the Brazilian exports were specified. The results were satisfactory and they match with the literature. The supply of exports presented a positive answer in relation to the exporter's remuneration, to the production, to the use of the installed capacity (cycles of domestic economical activity and to the tendency, and negative in relation to the internal demand. The demand for the Brazilian exports was influenced positively by the world income, participation index and tendency, and negatively for the relative price. The low elasticity-price of the found demand can have implications in the conservation of the Brazilian forest resources because the exporters can increase the prices, reduce the amounts and still increase the incomes.

      Ethanol has recently been of great interest worldwide because it is a viable economic alternative to petroleum products and it is a renewable source of energy that mitigates the emission of greenhouse gases. Brazilian bioethanol from sugarcane is the most successful case at the world level because of its low cost and low level of greenhouse gas emissions. Brazil's success with sugarcane cannot be understood as based solely on a natural comparative advantage, but as a result of efforts that culminated in a positive trajectory of technological learning, relying mostly on incremental innovations. The purpose of this article is to analyze the key aspects of the innovation system built around the Brazilian sugarcane industry. It is based on the national innovation systems approach according to which innovation results from the interaction of different institutional actors. Institutional arrangements are analyzed as the basis for the innovative process, in particular R and D and the innovation policies and strategies of the main players in the sugarcane sector, including sugar and ethanol mills, industrial goods suppliers, public and private research institutions, and governmental agencies. - Research Highlights: → The Brazilian success in bioethanol is due to the sugarcane innovation system. → Private funds for R and D became central after IAA closure. → Nowadays Brazilian innovation system is transforming to keep its leadership. → Public funds for research in the second generation bioethanol.

      The cyanobacterial community from Brazilian mangrove ecosystems was examined using a culture-dependent method. Fifty cyanobacterial strains were isolated from soil, water and periphytic samples collected from Cardoso Island and Bertioga mangroves using specific cyanobacterial culture media. Unicellular, homocytous and heterocytous morphotypes were recovered, representing five orders, seven families and eight genera (Synechococcus, Cyanobium, Cyanobacterium, Chlorogloea, Leptolyngbya, Phormidium, Nostoc and Microchaete). All of these novel mangrove strains had their 16S rRNA gene sequenced and BLAST analysis revealed sequence identities ranging from 92.5 to 99.7% when they were compared with other strains available in GenBank. The results showed a high variability of the 16S rRNA gene sequences among the genotypes that was not associated with the morphologies observed. Phylogenetic analyses showed several branches formed exclusively by some of these novel 16S rRNA gene sequences. BLAST and phylogeny analyses allowed for the identification of Nodosilinea and Oxynema strains, genera already known to exhibit poor morphological diacritic traits. In addition, several Nostoc and Leptolyngbya morphotypes of the mangrove strains may represent new generic entities, as they were distantly affiliated with true genera clades. The presence of non-ribosomal peptide synthetase, polyketide synthase, microcystin and saxitoxin genes were detected in 20.5%, 100%, 37.5% and 33.3%, respectively, of the 44 tested isolates. A total of 134 organic extracts obtained from 44 strains were tested against microorganisms, and 26% of the extracts showed some antimicrobial activity. This is the first polyphasic study of cultured cyanobacteria from Brazilian mangrove ecosystems using morphological, genetic and biological approaches. Copyright © 2014 Elsevier GmbH.

O Ministério da Saúde elegeu o Programa de Saúde da Família como a estratégia de transformação dos modelos assistenciais vigentes. Quase dez anos após seu início, constata-se uma grande heterogeneidade na sua implantação no país, com uma cobertura mínima em municípios de grande porte, notadamente nas capitais brasileiras. A expansão para as grandes cidades é condição, tanto para elevações mais significativas de cobertura populacional atingida pelo programa, como para que o PSF possa realmente vir a ser um elemento central na transformação do modelo assistencial do país.This article presents research results on implementation of the Family Health Program (PSF in large cities of Brazi!. lt discusses some of the specific difficulties in restructuring the health care model in large cities and in the adoption of the Programo lt thus serves as an introduction to the theme of this edition of Physis, analyzed in detail in the subsequent articles. The Brazilian Ministry of Health chose the Family Health Program as its strategy for transforming prevailing health care models. Almost ten years after the Program was launched, there is a great heterogeneity in its implementation around the country, with minimum coverage in large municipalities, especiany in the State capitals. Expansion of the PSF to the large cities is a condition both for attaining higher population coverage and for the Program to actuany become a key element in transforming the country's health care model.

    4. Study of multi-generational effects of a chronic exposure to ionizing radiations at a model organism: the nematode Caenorhabditis elegans

      The environmental risk assessment of chronic exposure to ionizing radiation (natural and ubiquitous phenomenon enhanced by human activities) has become a major concern. Few studies relating to chronic exposure over several generations - essential knowledge to better understand the disruption caused by ionizing radiation and its possible consequences on the population - exist. In addition, it has become necessary to understand the mechanisms of disturbances related to ionizing radiation at the molecular and cellular level. Without this mechanistic understanding, it is difficult to extrapolate the effects observed between the different levels of biological organization and between different species. The aim of this PhD was to study the multi-generational effects of chronic gamma radiation in an integrated manner (to the life history traits from the subcellular mechanisms) in a model organism, the nematode Caenorhabditis elegans. A two-step strategy was implemented. First, studying the effects of chronic gamma radiation on the life history traits of C. elegans was performed. The objective of this experiment was to test the hypothesis of an increase of the sensitivity according generations. For that, three generations have been exposed to different dose rates. In parallel, two generations have been placed in 'control' environment after parental exposure to test a possible transmission of maternal effects. The second part of this thesis aimed to characterize the different subcellular mechanisms that could explain the observed effects on the life history traits after multi-generational exposure. The results showed that (i) the cumulative number of larvae was the most sensitive endpoint to gamma radiation, (ii) an increase in radiosensitivity was observed over three exposed generations and (iii) the effects of the parental generation were transmitted to the non-exposed generations. An increase in apoptosis, a reduction in the stock of sperm, and to a lesser

      IMPORTANCE Esophageal adenocarcinoma and its precursor lesion Barrett esophagus have seen a dramatic increase in incidence over the past 4 decades yet marked genetic heterogeneity of this disease has precluded advances in understanding its pathogenesis and improving treatment. OBJECTIVE To identify novel disease susceptibility variants in a familial syndrome of esophageal adenocarcinoma and Barrett esophagus, termed familial Barrett esophagus, by using high-throughput sequencing in affected individuals from a large, multigenerational family. DESIGN, SETTING, AND PARTICIPANTS We performed whole exome sequencing (WES) from peripheral lymphocyte DNA on 4 distant relatives from our multiplex, multigenerational familial Barrett esophagus family to identify candidate disease susceptibility variants. Gene variants were filtered, verified, and segregation analysis performed to identify a single candidate variant. Gene expression analysis was done with both quantitative real-time polymerase chain reaction and in situ RNA hybridization. A 3-dimensional organotypic cell culture model of esophageal maturation was utilized to determine the phenotypic effects of our gene variant. We used electron microscopy on esophageal mucosa from an affected family member carrying the gene variant to assess ultrastructural changes. MAIN OUTCOMES AND MEASURES Identification of a novel, germline disease susceptibility variant in a previously uncharacterized gene. RESULTS A multiplex, multigenerational family with 14 members affected (3 members with esophageal adenocarcinoma and 11 with Barrett esophagus) was identified, and whole-exome sequencing identified a germline mutation (S631G) at a highly conserved serine residue in the uncharacterized gene VSIG10L that segregated in affected members. Transfection of S631G variant into a 3-dimensional organotypic culture model of normal esophageal squamous cells dramatically inhibited epithelial maturation compared with the wild-type. VSIG10L exhibited

Esta avaliação tomou como referência três dimensões: o acesso, a organização do trabalho e as estratégias de programação. Foram sorteados 19 municípios no estado. Os instrumentos de coleta foram a entrevista estruturada aplicada a gestores e dentistas, a observação estruturada e a pesquisa documental. Foi possível identificar precariedade nas relações de trabalho e dificuldades no referenciamento para média e alta complexidade, na intersetorialidade, no diagnóstico epidemiológico e na avaliação das ações. A maioria dos municípios apresentou pouco ou nenhum avanço no modelo assistencial em saúde bucal. Os municípios que demonstraram avanços apresentaram alta expectativa de vida ao nascer, baixas taxas de mortalidade infantil, valores per capita entre os mais altos do Estado e altos valores de IDH-M. Concluiu-se que políticas públicas que contemplam aspectos além dos pertinentes ao setor saúde são decisivas para uma real mudança nos modelos assistenciais.The purpose of this study was to evaluate the addition of oral health teams to the Family Health Program in the State of Rio Grande do Norte, Brazil, by analyzing factors that can affect the process of changing oral health care models.

      Full Text Available As in many national cinemas, the history of Brazilian amateur film is still in its early stages of investigation. In addition to this historiographical deficit, there are many ways in which amateur cinema is a small and less visible production: films shot in 16mm, 9.5mm and Super 8 are dispensable and Brazilian film archives and cinemateques only started cataloguing these materials in recent years. In the following paper we wish to establish a set of theoretic and historical guidelines to analyse amateur films that express different forms of amateur production. Through the collection of home movies from Alves de Lima family deposited at Cinemateca Brasileira (São Paulo, the amateur fictional films from Cinemateca Capitólio (Porto Alegre and Raymond Chauvin's  experimental films belonging to Hipólito José da Costa Communications Museum (Porto Alegre we want to give visibility to films that are not yet part of Brazilian cinema history.

      In this work, a novel integrated biomass based multigeneration energy system is presented and investigated for power, cooling and hydrogen production. The proposed system consists of a combination of biomass integrated gasifier-gas turbine cycle, a Rankine cycle, a cascade organic Rankine cycle, an absorption refrigeration system and a PEM to produce hydrogen. This system uses cold energy of LNG as a thermal sink. Comprehensive thermodynamic and economic analyses as well as an optimization are performed. The effects of operating parameters on thermodynamic performance and total cost rate are investigated for overall system and subsystems. The results show that the fuel mass flow rate is the dominant factor affecting the variation of energy efficiency and total cost rate. An increase in fuel mass flow rate from 4 kg s"−"1 to 10 kg s"−"1 leads to a decrease of 8.5% and an increase of 122.8% overall energy efficiency and total cost rate, respectively. Also, the largest increase in exergy efficiency occurs when gas turbine inlet temperature increases. The results of optimization showed that the highest net power output, mass flow rate of natural gas delivered to city and the flue gas temperature discharged to the environment are obtained for the exergy efficiency optimal design. - Highlights: • A novel multigeneration system is investigated and optimized thermodynamically and economically. • This system is proposed for power, cooling and hydrogen production. • Proposed system uses LNG cold energy thermal sink that can generate power after vaporization. • The effects of operating parameters on energy and exergy efficiencies and total cost rate are investigated. • An optimization is applied based on the energy, exergy and economic viewpoints.

      The path from Earth to Mars requires exploration missions to be increasingly Earth-independent as the foundation is laid for a sustained human presence in the following decades. NASA pioneering of Mars will expand the boundaries of human exploration, as a sustainable presence on the surface requires humans to successfully reproduce in a partial gravity environment independent from Earth intervention. Before significant investment is made in capabilities leading to such pioneering efforts, the challenges of multigenerational mammalian reproduction in a partial gravity environment need be investigated. The Multi-generational Independent Colony for Extraterrestrial Habitation, Autonomy, and Behavior health is designed to study these challenges. The proposed concept is a conceptual, long duration, autonomous habitat designed to house rodents in a partial gravity environment with the goal of understanding the effects of partial gravity on mammalian reproduction over multiple generations and how to effectively design such a facility to operate autonomously while keeping the rodents healthy in order to achieve multiple generations. All systems are designed to feed forward directly to full-scale human missions to Mars. This paper presents the baseline design concept formulated after considering challenges in the mission and vehicle architectures such as: vehicle automation, automated crew health management/medical care, unique automated waste disposal and hygiene, handling of deceased crew members, reliable long-duration crew support systems, and radiation protection. This concept was selected from an architectural trade space considering the balance between mission science return and robotic and autonomy capabilities. The baseline design is described in detail including: transportation and facility operation constraints, artificial gravity system design, habitat design, and a full-scale mock-up demonstration of autonomous rodent care facilities. The proposed concept has

      1990-01-01

      This paper focuses on studies and information related to the use of alternative fuels in Brazil. The first part of this paper deals with the economics of different biomass technologies. The analysis consists of a careful costing of all operations involved. The study deals with wood, sugar cane and cassava, since these crops are exploited for commercial purposes in Brazil. Corn, although a useful raw material for producing ethanol in the United States, is not used for this purpose in Brazil. The second part deals with the industrial technologies used to convert biomass into energy. We consider several forms of energy derived from biomass and evaluate the economics of the processes. When opportune, we compare costs with those of the North American market. Market analysis and displacement of conventional energy are the subject of the third part of the paper. While the cost of each product is evaluated in most cases; in others the current market price is used. Finally, we raise the issues of institutional problems and planning and offer some conclusions on the future of biomass as an alternative energy source. The technological discussion in this paper is based on the Brazilian experience in producing ethanol and other fuels from biomass. It is possible to extrapolate the Brazilian experience to other developing countries. The observations made in this chapter are based on the conditions prevalent in the Brazilian south-central agricultural region, specifically the state of Sao Paulo.

      Full Text Available In 1912 the Brazilian diplomat and scholar Manuel de Oliveira Lima gave six lectures at Stanford University that encapsulated his views of what we now call Brazilian Studies. This article summarizes Oliveira Lima’s lectures. It then points out three aspects of Oliveira Lima’s worldview that are problematic from the perspective of the twenty-first century: his Eurocentrism; the unproblematic nature of the nation-state in his thinking; and his largely negative view of Brazil’s racial heritage. The third part of the essay analyzes three aspects of Oliveira Lima’s lectures that are still contemporary. These are the need to establish an adequate comparative context for the study of Brazil; the difficulty of justifying an academic discipline that revolves around the study of a single country; and the challenge of uniting disparate and specialized disciplines in order to appreciate Brazil’s complexity and trajectory in the modern world. In the conclusion, some guidelines for maintaining Brazilian Studies as a vibrant field are suggested.

      The purpose of this study was to address the hypothesis that childhood apraxia of speech (CAS) is influenced by an underlying deficit in sequential processing that is also expressed in other modalities. In a sample of 21 adults from five multigenerational families, 11 with histories of various familial speech sound disorders, 3 biologically related adults from a family with familial CAS showed motor sequencing deficits in an alternating motor speech task. Compared with the other adults, these three participants showed deficits in tasks requiring high loads of sequential processing, including nonword imitation, nonword reading and spelling. Qualitative error analyses in real word and nonword imitations revealed group differences in phoneme sequencing errors. Motor sequencing ability was correlated with phoneme sequencing errors during real word and nonword imitation, reading and spelling. Correlations were characterized by extremely high scores in one family and extremely low scores in another. Results are consistent with a central deficit in sequential processing in CAS of familial origin.

      Full Text Available ABSTRACT Objective: To analyze the police reports filed by older adults who suffered abuse in order to identify the socio-demographic characteristics of victims and aggressors, type of violence, location, as well as to compare rates in three Brazilian cities in the period from 2009 to 2013. Method: Ecological study, in which 2,612 police reports registered in Police Stations were analyzed. An instrument was used to obtain data from the victim, the aggressor and the type of violence. Results: Psychological abuse predominated and most cases occurred in the older adults own home. In the cities of Ribeirão Preto and João Pessoa, the older adults presented similar rates for both gender. Regarding the standardized rates, in João Pessoa, there was a rise of this type of abuse in the two first years, and later there was a certain stability. In the city of Teresina, there was an increase, also observed in the city of Ribeirão Preto in the three first years, followed by a decrease. Conclusion: Older adults abuse is a cultural phenomenon difficult to be reported by them, since it occurs in the family context.

      It is recognized the economic benefits that might follow the opening process of the Brazilian oil and natural gas industry, which shall experience a fast expansion with the arrival of national and international private investors. However, we should not neglect the broader impact of this process on the future development of all that cluster of national agents that lived around and served the former national oil monopoly, managed by the Brazilian National Oil Company, Petrobras. This work focuses on this larger perspective, discussing about the capacity of Brazil to sustain and expand its competitiveness in the oil business as well as to obtain the maximum economic development from the exploration of its oil and gas reserves. We adopt the work of Michael Porter, from the University of Harvard, about the Competitive Advantage of Nations, as a theoretical model to analyze the Competitive Advantage of Brazil in the global oil industry. By introducing the concept of ''oil diamond'', adapted from the notion introduced by this author, we develop a new understanding of national competitiveness in the oil sector. In this paper, we present the general model as well as a brief characterization of the results found for Brazil Subsequently, we focus on just one leg of the model, for which we discuss, with more detail, about the competitive condition of the country in the opening-up scenario. This leg regards the so-called supporting and supplementary industries that constitute what is denominated in the French tradition the ''para petroleum'' industry. We analyze the conditions for the Brazilian domestic ''para petroleum industry'' to survive and grow in the new competitive environment. (authors)

Named as "dual career family", this phenomenon emphasizes a joint move from a husband and wife (a couple in the family sphere and in the development of both careers. Thus, in order to know how these relationships are being established, this study set out to investigate what are the determining factors that compose the dual career phenomenon in the Brazilian context. The research involved 340 participants, all former students of a public university, married or living in a marital status. The results allowed to feature, through descriptive statistics, the profile of dual career couples in the Brazilian scene and check what are the types of dual career in the country.

      Full Text Available O Brasil experimenta hoje a implementação de um modelo diferenciado para prover atenção básica à saúde, orientado por uma ação multidisciplinar na direção de uma intervenção voltada para a promoção da saúde da população e consubstanciada no Programa Saúde da Família. O objetivo de promover a saúde, especialmente no Brasil, não será alcançado sem que ações efetivas na área da vigilância e da assistência alimentar e nutricional sejam implementadas de forma articulada a um sistema de vigilância à saúde. Assim, este trabalho traz à luz algumas reflexões sobre a transição epidemiológica vivenciada no país e situa a problemática alimentar e nutricional nesse processo. Coloca ainda em relevo algumas das proposições básicas do Programa Saúde da Família e da Política Nacional de Alimentação e Nutrição e argumenta como o nutricionista pode contribuir para a necessária transformação, operando nas práticas e nos resultados desse novo modelo de intervenção. Por fim, destaca a impossibilidade de efetivamente transformar a atenção básica à saúde sem o apoio de profissionais que estudam, pesquisam e praticam cotidianamente a vigilância alimentar e nutricional e a assistência dietética e dietoterápica de indivíduos e populações.Brazil is presently experiencing the implementation of a differentiated model to provide health basic care, conduced by a multidisciplinary action directed towards an intervention aiming at then population health promotion, consolidated on the Brazilian Family Health Program.

      Painful peripheral neuropathy has been correlated with various voltage-gated sodium channel mutations in sensory neurons. Recently Nav1.9, a voltage-gated sodium channel subtype, has been established as a genetic influence for certain peripheral pain syndromes. In this study, we performed a genetic study in six unrelated multigenerational Japanese families with episodic pain syndrome. Affected participants (n = 23) were characterized by infantile recurrent pain episodes with spontaneous mitigation around adolescence. This unique phenotype was inherited in an autosomal-dominant mode. Linkage analysis was performed for two families with 12 affected and nine unaffected members, and a single locus was identified on 3p22 (LOD score 4.32). Exome analysis (n = 14) was performed for affected and unaffected members in these two families and an additional family. Two missense variants were identified: R222H and R222S in SCN11A. Next, we generated a knock-in mouse model harboring one of the mutations (R222S). Behavioral tests (Hargreaves test and cold plate test) using R222S and wild-type C57BL/6 (WT) mice, young (8-9 weeks old; n = 10-12 for each group) and mature (36-38 weeks old; n = 5-6 for each group), showed that R222S mice were significantly (p pain. The mouse model developed here will be useful for drug screening for familial episodic pain syndrome associated with SCN11A mutations.

    13. Publication in a Brazilian journal by Brazilian scientists whose papers have international impact.

      Meneghini, R

      2010-09-01

      Nine Brazilian scientists with an outstanding profile of international publications were invited to publish an original article in the same issue of a Brazilian Journal (Anais da Academia Brasileira de Ciências). The objective was to measure the impact of the papers on the number of citations to the articles, the assumption being that these authors would carry their international prestige to the Brazilian periodical. In a 2-year period there was a larger number of citations of these articles compared to others published in the same journal. Nevertheless, the number of citations in Brazilian journals did not equal the number of citations obtained by the other papers by the same authors in their international publications within the same 2-year period. The reasons for this difference in the number of citations could be either that less significant invited articles were submitted or that it was due to the intrinsic lack of visibility of the Brazilian journals, but this could not be fully determined with the present data. Also relevant was a comparison between the citations of Brazilian journals and the publication in Brazilian journals by these selected authors. A clear imbalance due to a remarkable under-citation of Brazilian authors by authors publishing in Brazilian journals raises the possibility that psychological factors may affect the decision of citing Brazilian journals.

      Full Text Available Abstract Background Differences in sex hormone levels among populations might contribute to the variation in breast cancer incidence across countries. Previous studies have shown higher breast cancer incidence and mortality among Japanese Brazilians than among Japanese. To clarify the difference in hormone levels among populations, we compared postmenopausal endogenous sex hormone levels among Japanese living in Japan, Japanese Brazilians living in the state of São Paulo, and non-Japanese Brazilians living in the state of São Paulo. Methods A cross-sectional study was conducted using a control group of case-control studies in Nagano, Japan, and São Paulo, Brazil. Participants were postmenopausal women older than 55 years of age who provided blood samples. We measured estradiol, estrone, androstenedione, dehydroepiandrosterone sulfate (DHEAS, testosterone and free testosterone by radioimmunoassay; bioavailable estradiol by the ammonium sulfate precipitation method; and sex hormone-binding globulin (SHBG by immunoradiometric assay. A total of 363 women were included for the present analyses, comprising 185 Japanese, 44 Japanese Brazilians and 134 non-Japanese Brazilians. Results Japanese Brazilians had significantly higher levels of estradiol, bioavailable estradiol, estrone, testosterone and free testosterone levels, and lower SHBG levels, than Japanese. Japanese Brazilians also had significantly higher levels of bioavailable estradiol, estrone and DHEAS and lower levels of SHBG and androstenedione than non-Japanese Brazilians. Levels of estradiol, testosterone and free testosterone, however, did not differ between Japanese Brazilians and non-Japanese Brazilians. These differences were observed even after adjustment for known breast cancer risk factors. We also found an increase in estrogen and androgen levels with increasing body mass index, but no association for most of the other known risk factors. Conclusions We found higher levels of

    15. German-Brazilian nuclear deal

      Krugmann, H.

      1981-01-01

      Examination of the arguments in favor of the nuclear deal with West Germany and the resulting program suggests that revisions of both are in order to make them more compatible with Brazil's national interests. The deficiencies of current policy appear to be too weighty and numerous to be ignored. Sooner or later the government will have to move toward adjusting its nuclear agreement with West Germany, if not for the reasons discussed here then for lack of capital. Current estimates of the nuclear package lie in the range of $25 to $30 billion, compared to an initial projection of about $5 billion. The deal has become so expensive that it would draw capital from the hydropower and alcohol programs essential for the short and medium-term energy needs of the country. Mr. Krugman feels the Brazilian government should hold off on further nuclear contracts. And it should thoroughly reassess what Brazil's nuclear energy and technology requirements are and how to meet them. There are indications that the reassessment process is already underway. As long as the German nuclear industry depends on the sale of technology to Brazil, the Brazilian government will have considerable bargaining power to enforce further changes in the deal. If this power is used wisely, the result could be cooperation between the two countries toward nuclear options that are consistent with Brazil's energy and development needs

      Full Text Available Migration to well-off countries has been well documented. However, the reasons why migrants return to their home countries, which often face severe economic disadvantages, are examined less frequently. The return migration ofJapanese-Brazilians (Brazilian citizens of ethnic Japanese descent who migrate to Japan and return again to Brazil has not been studied to any great extent. To understand the factors associated with Japanese-Brazilians’ return migration, using Gmelch's (1983 model of push and pull factors, we examined what motivated Japanese-Brazilian migrant laborers to return to Brazil from Japan.With a mixed method including in-person interviews, a total of n=47 Brazilian migrants to Japan were sampled in São Paulo, Brazil. The present examination resulted in a pattern similar to the one Gmelch (1983 observed in his study on Irish and Newfoundlander return migrants. In the current study, pull factors were more important than push factors in terms of repatriation. Personal and social pull factors were stronger reasons compelling migrants return to Brazil than were economic or familial factors. Nevertheless, familial and economic reasons were also reported as important motivators for returning to Brazil in our interviews. Limitations are also discussed.

      Full Text Available The objective of this study was to explore the evolution of internal and external commercialization of Brazilian sparkling wines during the period between 1986 and 2015, giving an overview of the current situation and its market trends, and highlighting the importance of Brazil in the world scenario for sparkling wines. This research is based on quantitative data sources provided by different institutions: International Organization of Vine and Wine (OIV, Brazilian Union of Viticulture (UVIBRA, Ministry of Agriculture, Livestock and Supply (MAPA and Brazilian Agricultural Research Corporation (EMBRAPA. Brazil is a promising country for the sparkling wine market. From 1986–2015, there was an increase of 465.6% in the sales of sparkling wine in the Brazilian domestic market, especially the last ten, which accounted for an increase of 215.7%. In 1998, Brazilian sparkling wines accounted for 70.5% of sparkling wines sold in Brazil. Today, they represent 82.1%of national market, and proved to be one of the most prestigious products from Brazilian viticulture when compared, for example, to non-sparkling wines, which 79% are imported wines. Of the imported sparkling wines consumed in Brazil, six countries account for 98.5% of the market (France: 32.7%; Italy: 24.8% and Spain: 21.9%. The volume exportation of Brazilian sparkling wine has grown significantly in recent years (4,210.2%, with Paraguay, China, Uruguay, the United States, France and the United Kingdom being the major buyers. The evolution of exports shows that Brazilian sparkling wine becomes an alternative to those produced in traditional countries, such as France, Italy and Spain, due to their quality and price. There is an increase in the commercialization of sparkling wines in the Brazilian domestic market, in addition to the growing participation of Brazil in the volume of exports in the world market, placing Brazil in a leading position in the production and sale of sparkling wines.

      The purpose of this study is to present an understanding of the experience of Brazilian homemakers with type 2 diabetes mellitus (DM2). A descriptive exploratory design was used and semi-structured interviews were conducted with 25 Brazilian homemakers concerning their experience. The interviews were recorded, transcribed, and the resulting text was analyzed using the sequential step method. Data converged to one dominant category, "constructing one's identity in the family context", which is comprised of three categories: gender differences; day-to-day concerns; and incongruity between knowledge and behavior related to DM2. These findings suggest that participants construct their identities within the family context and that their experience of living with DM2 is integral to their self-identification as wives and mothers. This, in turn, has implications for the design and implementation of programs to assist women in managing DM2 effectively.

      Full Text Available Elicited imitation (EI is an approach to measuring oral proficiency that consists of having test takers hear a sentence and repeat the sentence exactly as they heard it. Though indirect in nature, EI has successfully shown to correlate with previously established oral proficiency examinations, such as the Oral Proficiency Interview (OPI (Lonsdale and Christensen 2014, Matsushita and Lonsdale 2014, Millard 2011, Thompson 2013. This paper discusses the development, administration, and evaluation of an EI test for the Brazilian Portuguese language. We first discuss the relevant background of oral proficiency examination and EI. After presenting the pertinent research questions, we explain the methodology used to develop the EI test, recruit participants, and administer the test. We present the results and analysis and then summarize the findings, limitations, and possible future work

      Full Text Available Neolatin languages belong to a lexicalization pattern in which the verbal root expresses semantic primitives of MOVE and PATH, leaving MANNER or CAUSE to be expressed by an adverb or the gerund form. In German origin languages, on the contrary, verbs lexicalize the semantic primitives of MOVE, MANNER or CAUSE; as for the PATH, it is expressed by a grammatical element that is associated to the verb. Taking into consideration some of the concepts of event of move, guided by Cognitive Semantics, and an analysis of examples extracted from The Hobbit and The Lord of the Rings’ books, the present study aims at showing, at least, three lexicalization patterns in which Brazilian Portuguese fits in.

      The National Center for Toxicological Research (NCTR) is the basic research arm of the US Food and Drug Administration (FDA). The NCTR has upgraded and standardized its computer operations on Digital Equipment Corporation VAX minicomputers using Software AG's ADABAS data base management system for all research applications. The NCTR is currently performing a large study to improve the functionality of the animal husbandry systems and applications called Breeding/Multigeneration Support System (BMSS). When functional, it will operate on VAX equipment using the ADABAS data base management system, TDMS, and COBOL. Oak Ridge National Laboratory (ORNL) is supporting NCTR in the design, prototyping, and software engineering of the BMSS. This document summarizes the internal design elements that include data structures, file structures, and system attributes that were required to facilitate the decision support requirements defined in the external design work. Prototype pseudocode then was developed for the recommended system attributes and file and data structures. Finally, ORNL described the processing requirements including the initial access of the BMSS, integration of the existing INLIFE system and the STUDY DEFINITION system under development, data system initialization and maintenance, and BMSS testing and verification. This document describes ORNL's recommendations for the internal design of the BMSS. ORNL will provide research support to NCTR in the additional phases of systems life cycle development for BMSS.

      Full Text Available Introduction: Although the quality of parent-child relationships is known to be associated with the offspring's mental health, little is known about the prevalence of problematic relationships in this scenario. This cross-sectional study aims to investigate the prevalence and risk factors of different types of early parent-infant relationships in a Brazilian population group. Methods: During 1 year, all families (n = 230 from an urban community of Porto Alegre, southern Brazil, with 4-month-old infants born in public hospitals were identified, and 148 were fully investigated by two family therapists. This study describes data on the 116 infants with two-parent families. Demographic, obstetric, and relational variables were collected through questionnaires and scales (Parent-Infant Relationship Global Assessment Scale, Global Assessment of Relational Functioning, and Self-Report Questionnaire. Prevalence ratios were calculated, and Poisson regression with robust variance was performed to adjust for covariates. Results: Almost 10% of mothers and 12% of fathers showed at least a significantly perturbed relationship with their 4-month-old infants. Inadequate mother-infant bonding coincided with evidence of paternal mental disorder, poor maternal social network, and discontinuation of breastfeeding at 4 months. A problematic father-infant relationship was associated with a dysfunctional couple relationship and with low infant birth weight. Conclusions: There is a high prevalence of early parent-child relationship problems, suggesting a need for health system interventions. Parent-infant relational problems are prevalent very early in life and more associated with other relational problems than with socioeconomic burden.Introdução: Embora seja consenso que a qualidade das relações pais-filho influencie a saúde mental da prole, pouco se sabe sobre a prevalência de relações problemáticas nessa esfera.

      Full Text Available Significant progress has been obtained since the Second Brazilian Consensus Conference on Helicobacter pylori Infection held in 2004, in São Paulo, SP, Brazil, and justify a third meeting to establish updated guidelines on the current management of H. pylori infection. The Third Brazilian Consensus Conference on H pylori Infection was organized by the Brazilian Nucleus for the Study of Helicobacter, a Department of the Brazilian Federation of Gastroenterology and took place on April 12-15, 2011, in Bento Gonçalves, RS, Brazil. Thirty-one delegates coming from the five Brazilian regions and one international guest, including gastroenterologists, pathologists, epidemiologists, and pediatricians undertook the meeting. The participants were allocated in one of the five main topics of the meeting: H pylori, functional dyspepsia and diagnosis; H pylori and gastric cancer; H pylori and other associated disorders; H pylori treatment and retreatment; and, epidemiology of H pylori infection in Brazil. The results of each subgroup were submitted to a final consensus voting to all participants. Relevant data were presented, and the quality of evidence, strength of recommendation, and level of consensus were graded. Seventy per cent and more votes were considered as acceptance for the final statement. This article presents the main recommendations and conclusions to guide Brazilian doctors involved in the management of H pylori infection.

    1. Futebol mulato: racial constructs in Brazilian football

      Directory of Open Access Journals (Sweden)

      Tiago Fernandes Maranhao

      2011-05-01

      Full Text Available The aim of this paper is to review Gilberto Freyre’s ideas about futebol mulato and the way these ideas have spread the notion of the Brazilian mulatto as a symbol of a ‘racial democracy’, unique in Brazil, around the world. The notion first appeared in 1938 in an article by Freyre for the Diários Associados, an important Brazilian newspaper. Football (soccer was employed by Freyre as the special arena where the multiracial Brazilian nation could shine and show the world a different way of being, opposed to the white and ‘rational’ way of European football. In Freyre’s work, the so-called ‘football-art’ was compared to poetry, while the European style was equated with prose. This essay argues that Freyre’s ideas were useful in constructing the Brazilian identity, a nation of harmony in all its aspects, including the area of race, and how the idea of the mulatto has been used to minimise social disparities within Brazilian society. Freyre’s ideas remain contemporary; many Brazilian intellectuals still refer to these concepts. As well, the press in this huge country, and especially in World Cup years, uses the concepts of mulatto and football-art to characterize Brazil and differentiate it from other countries.

      The elderly suffering disability caused by diseases need a network of support in order to continue feeling socially active. This study aims at characterizing the social support provided to the family caregiver who looks after an elderly dependent, in Brazil. A descriptive study with qualitative approach was conducted at the municipality of Jandaia do Sul, Paraná, Brazil. Data collection was performed through semi-structured interviews with 19 primary family caregivers. Data analysis was based on Thematic Analysis. The results show that when it comes to informal sources, the reference to grown up children was mostly used, while as formal ones Unidade Básica de Saúde, the Brazilian Basic Health Unit, and the team from Programa Saúde da Familia, Brazilian Pro-Family Health Program, were referred to. However, the image of Community Health Agent was the most mentioned. Thus, it is necessary to create support nets to integrate both formal and informal systems.

      This study aimed to determine what Brazilian childless women of reproductive age think about oocyte cryopreservation to postpone pregnancy and their reasons for performing or not performing this procedure. Women of reproductive age were randomly selected from the general population using different e-mail lists and were invited to participate in the study by completing an online web survey regarding social oocyte cryopreservation. The survey was also distributed through social media to women of reproductive age. Although most of the responders had a partner (86.9%) and had already planned the pregnancy of their first child (69.6%), 85.4% (379) considered the potential of social oocyte freezing to improve their chances of giving birth later in life. Those that had already planned pregnancy were two times more likely to intend to freeze their oocytes (p=0.03). The most important barrier for not undergoing oocyte cryopreservation was cost. The women who indicated that they could not currently undergo the procedure now because of cost were two times (p=0.03) more likely to intend to cryopreserve their oocytes than women who thought that they would not need to delay pregnancy. Brazilian women who think that they are not ready to have a family are discovering the option of oocyte cryopreservation. Most participants considered safeguarding their reproductive potential. Making the procedure more accessible could give women the opportunity to make proactive decisions about the future of their fertility.

      Medication adherence is related to patient satisfaction with family support. This research aimed to understand the meaning of pharmacotherapy to families of people with major depressive disorder. This qualitative study employed Grounded Theory and Symbolic Interactionism. Seventeen families of people with depression from a Brazilian clinic were included. Data was collected from 2013 to 2014, using open interviews, which were analyzed by open, axial, and selective coding. Medication represented "Tranquility and worry" because it re-established tranquility in family routine, but generated concerns. Thus, families were conflicted and ambivalent about medications, and they interfered with the promotion or impairment of adherence.

      Family privilege is defined as "strengths and supports gained through primary caring relationships." A generation ago, the typical family included two parents and a bevy of kids living under one roof. Now, every variation of blended caregiving qualifies as family. But over the long arc of human history, a real family was a…

      Substantial ongoing research continues to explore the contribution of genetics and environment to the onset, extent and severity of periodontal disease(s). Existing evidence supports that periodontal disease appears to have an increased prevalence in family units with a member having aggressive periodontitis. We have been using the nonhuman primate as a model of periodontal disease for over 25 years with these species demonstrating naturally occurring periodontal disease that increases with age. This report details our findings from evaluation of periodontal disease in skulls from 97 animals (5-31 years of age) derived from the skeletons of the rhesus monkeys (Macaca mulatta) on Cayo Santiago. Periodontal disease was evaluated by determining the distance from the base of the alveolar bone defect to the cemento-enamel junction on 1st/2nd premolars and 1st/2nd molars from all four quadrants. The results demonstrated an increasing extent and severity of periodontitis with aging across the population of animals beyond only compensatory eruption. Importantly, irrespective of age, extensive heterogeneity in disease expression was observed among the animals. Linking these variations to multi-generational matriarchal family units supported familial susceptibility of periodontitis. As the current generations of animals that are descendants from these matrilines are alive, studies can be conducted to explore an array of underlying factors that could account for susceptibility or resistance to periodontal disease. © 2016 Wiley Periodicals, Inc.

      2009-01-01

      The objective of this article is to analyze the Brazilian Biodiesel Policy (PNPB) and to identify the social and environmental aspects of sustainability that are present or absent within it. Biofuels, namely alcohol and biodiesel, have been increasing in popularity on a global scale due to their potential as alternative and renewable energy sources. Brazil, a vast country blessed with abundant natural resources and agricultural land, has emerged as a global leader in the production of biofuels. This article includes a brief analysis of the concept of sustainable development, which served as a basis to evaluate the Policy documents. Although PNPB's implementation, which began in 2004, is still within its initial stage, it was possible to identify and elaborate on the environmental and social aspects of the Policy, namely: the social inclusion of family farmers; regional development; food security; influencing the carbon and energy balance of biodiesel; promoting sustainable agricultural practices and a diversity of feedstock.

      This study presents the helminth composition and parameters of infection by several species of nematodes in teiid lizards, Ameiva ameiva ameiva (Linnaeus, 1758), Cnemidophorus cryptus Cole and Dessauer, 1993, and Kentropyx calcarata Spix, 1825 from the Brazilian Amazonian Rainforest. The population of lizards studied were parasitized by 6 species of Phylum Nemata including: Spinicauda spinicauda (Olfers, 1919), Parapharyngodon alvarengai Freitas, 1957, Physaloptera sp. (adults), Physaloptera sp. (larvae), Piratuba digiticauda Lent and Freitas, 1941, and Anisakidae (larvae). The overall prevalence was 66.17% and the mean intensity of infection was 19.40 ± 25.48. The association between the body-length of lizards and the abundance and richness of parasitic nematodes was statistically significant only in Ameiva a. ameiva. A new host record is reported here with 1 specimen of the family Anasakidae in Ameiva a. ameiva. Both S. spinicauda and Physaloptera sp. represent new records from C. cryptus.

      Full Text Available Cerrado is the Brazilian name for the neotropical savanna, which occurs mainly in Brazilian Central Plateau, composed of herbaceous-subshrubby and shrubby-arboreal floras, both of which are heliophilous, highly diverse and regionally differentiated. Considering species distribution and chromosome numbers, some authors have proposed that the herbaceous-subshrubby flora of the neotropical savanna is quite old, while the shrubby-arboreal flora is derived from forests, a hypothesis that implies higher chromosome numbers in the savanna than in the forest. If, however, chromosome numbers are similar in the cerrado and in forests, both could be similarly old, indicating that bi-directional flow of flora occurred in the past. This paper presents data on chromosome numbers and microsporogenesis for 20 species in 13 families collected in the States of São Paulo, Goiás and Minas Gerais, providing previously unpublished data for Myrcia (Myrtaceae, Luxemburgia (Ochnaceae and Hortia (Rutaceae. Meiosis proved to be normal, indicating regularity in the sexual reproductive process. Chromosome numbers varied from 2n = 18 (Allamanda angustifolia: Apocynaceae to 2n = ca. 104 (Ouratea spectabilis: Ochnaceae, being low (20 Cerrado é a palavra que, no Brasil, designa a savana neotropical, com área nuclear no Planalto Central, constituída de uma flora herbáceo-subarbustiva e outra arbustivo-arbórea, ambas heliófilas, altamente diversificadas e regionalmente diferenciadas. Considerando a distribuição de espécies e de números cromossômicos, alguns autores propuseram que a flora herbáceo-subarbustiva da savanna neotropical seria bastante antiga, enquanto a flora arbustivo-arbórea seria derivada das florestas Atlântica e Amazônica, uma hipótese que implica na ocorrência de números cromossômicos mais altos no cerrado que nas florestas. Porém, se os números cromossômicos forem similares no cerrado e nas florestas, ambos os tipos de formação poderiam

      Sexual crime is an important public health concern. The possible causes of sexual aggression, however, remain uncertain. We examined familial aggregation and the contribution of genetic and environmental factors to sexual crime by linking longitudinal, nationwide Swedish crime and multigenerational family registers. We included all men convicted of any sexual offence (N = 21,566), specifically rape of an adult (N = 6131) and child molestation (N = 4465), from 1973 to 2009. Sexual crime rates among fathers and brothers of sexual offenders were compared with corresponding rates in fathers and brothers of age-matched population control men without sexual crime convictions. We also modelled the relative influence of genetic and environmental factors to the liability of sexual offending. We found strong familial aggregation of sexual crime [odds ratio (OR) = 5.1, 95% confidence interval (CI) = 4.5-5.9] among full brothers of convicted sexual offenders. Familial aggregation was lower in father-son dyads (OR = 3.7, 95% CI = 3.2-4.4) among paternal half-brothers (OR = 2.1, 95% CI = 1.5-2.9) and maternal half-brothers (OR = 1.7, 95% CI = 1.2-2.4). Statistical modelling of the strength and patterns of familial aggregation suggested that genetic factors (40%) and non-shared environmental factors (58%) explained the liability to offend sexually more than shared environmental influences (2%). Further, genetic effects tended to be weaker for rape of an adult (19%) than for child molestation (46%). We report strong evidence of familial clustering of sexual offending, primarily accounted for by genes rather than shared environmental influences. Future research should possibly test the effectiveness of selective prevention efforts for male first-degree relatives of sexually aggressive individuals, and consider familial risk in sexual violence risk assessment.

      2016-07-01

      Full Text Available This paper aims to highlight how the Brazilian press has been addressing the re-election process and impeachment concerning the government of President Dilma Rousseff. To achieve this objective, the newspaper O Globo, in its electronic version, was selected since it addresses both national and international issues and has a more significant exposure than other existing media in the country. In this regard, the newspaper has been publishing several reports about the current Brazilian political context considering the government Dilma Rousseff during the first and second presidential terms. The events of re-election and the process of impeachment were presented in a particular way by the selected newspaper, focusing on the construction of a negatively distorted image of both the president and the government in question. This construction has shown a given editorial position upon the domestic political conjuncture. Firstly, the article addresses reflections on the influence of the media on the formation of political perceptions in/about the Brazilian scene. Secondly, it analyses the approach of the newspaper concerning the aforementioned subject matter. Finally, it stresses the importance of the diversification of means of media, which still remain under monopoly of few family companies. These three questions point to not only a deeper view of the democratic experience, but also the relevance of political and ideological plurality in the contemporary Brazilian society.

    13. The Brazilian electrical system reform

      1999-01-01

      Although the Brazilian electrical system has been a public monopoly, the threat of electricity shortages from a lack of investment triggered a comprehensive reform. In 1993 the government began a series of laws, decrees and regulations reforming the tariff policy, allowing privatization of utilities, foreign investments and independent power producers, and creating an independent transmission grid and a new electricity regulatory agency (ANEEL). The new regulatory framework is not completely defined but the proposed model intends to transform bulk electricity supply into a competitive market similar to that adopted in England. Our objective is to evaluate whether the proposed reform will succeed in attracting the required private capital, will allow an unregulated wholesale electricity market and will require a strict regulatory framework. The reform has been quite successful in privatizing the distribution companies but is allowing monopolistic rents, and has failed until now to attract private investments to expand generation capacity. The risk of blackouts has increased, and the proposed wholesale electricity market may not be appropriate because of barriers to constructing new hydroelectric units, now 90% of the system. Therefore, a new regulatory framework and a strong regulatory agency with a well-defined tariff policy should have preceded the privatization. (author)

      In 1985 an opportunity arose for maintaining tracts of Amazonian forest under sustainable use. Brazil's National Council of Rubber Tappers and the Rural Worker's Union proposed the creation of a set of reserves of a new type, called extractive reserves. The first six are being established in one of the Brazilian states most threatened by deforestatation. The creation of extractive reserves grants legal protection to forest land traditionally used by rubber tappers, Brazil-nut gatherers, and other extractivists. The term extrativismo (extractivism) in Brazil refers to removing nontimber forest products, such as latex, resins, and nuts, without felling the trees. Approximately 30 products are collected for commercial sale. Many more types of forest materials are gathered, for example as food and medicines, for the extractivists' own use. The reserve proposal is attractive for several reasons related to social problems. It allows the rubber tappers to continue their livelihood rather than be expelled by deforestation. However, it is unlikely that sufficient land will be set aside as extractive reserves to employ all the tappers. Displaced rubber tappers already swell the ranks of urban slum dwellers in Brazil's Amazonian cities, and they have become refugees to continue their profession in the forests of neighboring countries, such as Bolivia.

      Full Text Available The permeability of Brazilian Eucalyptus grandis and Eucalyptus citriodora wood was measured in a custom build gas analysis chamber in order to determine which species could be successfully treated with preservatives. Liquid permeability was tested using an emulsion of Neen oil and a control of distillated water. Air was used to test the gas phase permeability. For both Eucalyptus grandis and Eucalyptus citriodora, the longitudinal permeability of gas was shown to be about twice as great as the liquid phase permeability. No radial permeability was observed for either wood. The permeability of air and water through the sapwood of Eucalyptus grandis was greater than that through the sapwood of Eucalyptus citriodora. The permeability of neen oil preservative through the sapwood of Eucalyptus grandis was also greater than through the sapwood of E. Citradora, but the difference was not statistically significant. Scanning Electron Microscopy images showed that the distribution and obstruction in the vessels could be correlated with observed permeability properties. Irrespective of the causes of differences in permeability between the species, the fluid phase flux through the sapwood of both species was significant, indicating that both Eucalyptus grandis and Eucalyptus citriodora could be successfully treated with wood preservative.

      A total of 2152 Actinobacteria strains were isolated from native Cerrado (Brazilian Savannah) soils located in Passos, Luminárias, and Arcos municipalities (Minas Gerais State, Brazil). The soils were characterised for chemical and microbiological analysis. The microbial analysis led to the identification of nine genera (Streptomyces, Arthrobacter, Rhodococcus, Amycolatopsis, Microbacterium, Frankia, Leifsonia, Nakamurella, and Kitasatospora) and 92 distinct species in both seasons studied (rainy and dry). The rainy season produced a high microbial population of all the aforementioned genera. The pH values of the soil samples from the Passos, Luminárias, and Arcos regions varied from 4.1 to 5.5. There were no significant differences in the concentrations of phosphorus, magnesium, and organic matter in the soils among the studied areas. Samples from the Arcos area contained large amounts of aluminium in the rainy season and both hydrogen and aluminium in the rainy and dry seasons. The Actinobacteria population seemed to be unaffected by the high levels of aluminium in the soil. Studies are being conducted to produce bioactive compounds from Actinobacteria fermentations on different substrates. The present data suggest that the number and diversity of Actinobacteria spp. in tropical soils represent a vast unexplored resource for the biotechnology of bioactives production.

      An increased health problem in industrialised countries is the contemporary concern of public and scientific community as well. This has been attributed in part to accumulated environmental pollutants especially radioactive substances and the use of nuclear power plants worldwide. However, the outcome of chronic exposure to low doses of a radionuclide such as uranium remains unknown. Recently, a paradigm shift in the perception of risk of radiotoxicology has emerged through investigating the possibility of transmission of biological effects over generations, in particular by epigenetic pathways. These processes are known for their crucial roles associated with the development of several diseases. The current work investigates the epigenetic effect of chronic exposure to low doses of uranium and its inheritance across generations. Materials and Methods To test this proposition, a rodent multigenerational model, males and females, were exposed to a non-toxic concentration of uranium (40mgL -1 drinking water) for nine months. The uranium effects on were evaluated over three generations (F0, F1 and F2) by analysing the DNA methylation profile and DNMT genes expression in ovaries and testes tissues. Here we report a significant hypermethylation of testes DNA (p <0.005) whereas ovaries showed hypomethylated DNA (p <0.005). Interestingly, this DNA methylation profile was significantly maintained across generations F0, F1 and F2. Furthermore, qPCR results of both tissues imply a significant change in the expression of DNA methyltransferase genes (DNMT 1 and DNMT3a/b) as well. Altogether, our work demonstrates for the first time a sex-dependance and inheritance of epigenetic marks, DNA methylation, as a biological response to the exposure to low doses of uranium. However, it is not clear which type of reproductive cell type is more responsive in this context. Copyright © 2017 Elsevier B.V. All rights reserved.

    19. Multi-Generational Kinship, Multiple Mating, and Flexible Modes of Parental Care in a Breeding Population of the Veery (Catharus fuscescens, a Trans-Hemispheric Migratory Songbird.

      Directory of Open Access Journals (Sweden)

      Matthew R Halley

      Full Text Available We discovered variable modes of parental care in a breeding population of color-banded Veeries (Catharus fuscescens, a Nearctic-Neotropical migratory songbird, long thought to be socially monogamous, and performed a multi-locus DNA microsatellite analysis to estimate parentage and kinship in a sample of 37 adults and 21 offspring. We detected multiple mating in both sexes, and four modes of parental care that varied in frequency within and between years including multiple male feeders at some nests, and males attending multiple nests in the same season, each with a different female. Unlike other polygynandrous systems, genetic evidence indicates that multi-generational patterns of kinship occur among adult Veeries at our study site, and this was corroborated by the capture of an adult male in 2013 that had been banded as a nestling in 2011 at a nest attended by multiple male feeders. All genotyped adults (n = 37 were related to at least one other bird in the sample at the cousin level or greater (r ≥ 0.125, and 81% were related to at least one other bird at the half-sibling level or greater (r ≥ 0.25, range 0.25-0.60. Although our sample size is small, it appears that the kin structure is maintained by natal philopatry in both sexes, and that Veeries avoid mating with close genetic kin. At nests where all adult feeders were genotyped (n = 9, the male(s were unrelated to the female (mean r = -0.11 ± 0.15, whereas genetic data suggest close kinship (r = 0.254 between two male co-feeders at the nests of two females in 2011, and among three of four females that were mated to the same polygynous male in 2012. To our knowledge, this is the first evidence of polygynandry occurring among multiple generations of close genetic kin on the breeding ground of a Nearctic-Neotropical migratory songbird.

      Studies on mammals and poultry showed that maternal dietary treatments can alter the offspring performance. However, in contrast to rodent studies, little is known about multigenerational dietary manipulations in broiler breeders. The presented research aimed to investigate the effects of a reduction of 25% in the dietary crude protein (CP) level in the F0 generation on the body composition and reproductive performance of F1 broiler breeders. In the F0 generation, breeders were fed either a control (C) or reduced balanced protein (RP) diet, 25% reduction in crude protein and amino acids. Female F0-progeny of each treatment were fed a C or RP diet, resulting in 4 treatments in the F1 breeder generation: C/C, C/RP, RP/C, and RP/RP. The reproductive performance of breeders fed RP diets was negatively influenced by the dietary CP reduction in the F1 generation (P diets in the F0 generation showed a significantly reduced reproductive capacity compared to their control fed counterparts (P diets in the F1 generation were characterized by higher plasma T3 concentrations (P diets in the F0 generation needed lower feed allocations in the laying phase to maintain a similar body weight. Egg weight was reduced for the C/RP and RP/RP breeders. At 34 wk of age, eggs from C/RP and RP/RP breeders showed a reduced proportional albumen weight, whereas no effects on egg composition were found at 42 wk of age. It was concluded that prenatal protein undernutrition triggered hens to relocate more energy towards growth and maintenance and less towards reproductive capacity.

    1. Assessment of 17α-ethinylestradiol effects and underlying mechanisms in a continuous, multigeneration exposure of the Chinese rare minnow (Gobiocypris rarus)

      17α-Ethinylestradiol (EE 2 ) is a synthetic estrogen used primarily in birth control pills and in hormone replacement therapy. Owing to its occurrence in surface waters at concentrations frequently greater than 1 ng/l and its projected future use, EE 2 is expected to pose a significant risk to aquatic organisms. This study was conducted to obtain long-term exposure data necessary for the establishment of water quality criteria and to investigate mechanisms associated with toxic effects. In a multigeneration experiment, Chinese rare minnows (Gobiocypris rarus) were constantly exposed to environmentally relevant concentrations of the synthetic estrogen EE 2 . Mortality, deformities, reproductive parameters, plasma vitellogenin and histopathology were assessed. The results showed that, in the F 0 generation, all endpoints were significantly affected at concentrations higher than 0.2 ng/l EE 2 . No F 1 phenotypic males developed to maturity at 0.2 ng/l and, when adult females of this exposure group were crossed with unexposed males, no F 2 fertile eggs were produced. Kidney histopathology and ultrastructure suggest anomalies possibly associated with increased vitellogenin accumulation. We concluded that the reproduction of the F 1 minnows was completely inhibited at the lowest concentration tested, 0.2 ng/l EE 2 , a concentration frequently detected in surface waters. Growth effects may be related to increased energy requirements including the energy used in VTG synthesis. Reproductive effects are presumably associated with male feminization and the occurrence of testis-ova in males; however, ovarian degeneration observed in females may also have contributed to reproductive failure

      The acronym IDEALS summarizes family physicians' obligations when violence is suspected: to identify family violence; document injuries; educate families and ensure safety for victims; access resources and coordinate care; co-operate in the legal process; and provide support for families. Failure to respond reflects personal and professional experience and attitudes, fear of legal involvement, and lack of knowledge. Risks of intervention include physician burnout, physician overfunctioning, escalation of violence, and family disruption. PMID:21228987

      Full Text Available Reflecting on the importance of multiculturalism in teaching process and observing the otherness are primarily a challenge. This enables us to rethink what we have within ourselves, also to reconstitute memories involving discriminatory and unethical attitudes, which takes place in social fellowship. Based on the studies of Walsh (2007, 2009, Gomes (2007 and Tavares (2011, this work relies on decoloniality studies, mainly on the relevance of the history of Africa and Africanness in Brazilian education. Our corpus of analysis is found in the "Diretrizes Curriculares Nacionais para a Educação Básica" (DCN, 2013, the Brazilian Legislative Syllabus for Basic Education. Our focus is on the chapters concerning the Native-Brazilian and Quilomboa Education and ethnic-racial relations. Our most important aims are: to show the intercultural theoretical framework in which they are based on; to understand the immediate link established between the Native-Brazilian education and intercultural perspective; to clarify how the African diaspora was carried out in this particular case. Based on some Excel resources we were able to: 1 stablish the predominance of functional framework of interculturalism throughout these chapters, along with some critical features of interculturalism, as the issue of curricular decoloniality; 2 observe the established relationship between bilingualism and multiculturalism in the guidelines of Native-Brazilian education; and 3 identify a search for an effective inclusion of Africanness in curricula supported by the historical recognition and visibility of their sociocultural contribution.

      Brazilian society declares no intention to development a nuclear artifact. This is on its Constitution. The submarine of nuclear propulsion may be used as a weapon of defense and, therefore, has a peaceful objective. Nationalism must be applied only to benefit the society. Nationalist attention has always been devoted, at various occasions, to the Brazilian nuclear sector. However, since Brazilian society has many needs and the Brazilian government always had numerous energy options, this sector has not been developed as it could be. Other successful applications of nuclear technology, besides electric generation, are not considered here. At present, the country is experiencing a moment of harassment of liberal forces. It is difficult to know if the population understands what is going on, due to the traditional media control. This media belongs to the capital. The rise and the fall of the nationalist strand in a country follow a global tendency and also depend of actions of the international capital. In nationalist periods, more decisions with positive social impact are taken. Therefore, sovereignty is necessary to increase the benefits to society. Unfortunately, the Brazilians deceived by the companies of mass communication and corrupt political leaderships allow the country to be dominated. Even the armed forces had their projects paralyzed. The nuclear sector, as all other, suffers with the low budget and the future is difficult to predict. (author)

      Ionizing radiation in Brazil is used in electricity generation, medicine, industry, agriculture and for research and development purposes. All these activities can generate radioactive waste. At this point, in Brazil, the use of nuclear energy and radioisotopes justifies the construction of a national repository for radioactive wastes of low and intermediate-level. According to Federal Law No. 10308, Brazilian National Commission for Nuclear Energy (CNEN) is responsible for designing and constructing the intermediate and final storages for radioactive wastes. Additionally, a restriction on the construction of Angra 3 is that the repository is under construction until its operation start, attaining some requirements of the Brazilian Environmental Regulator (IBAMA). The RBMN Project (Repository for Low and Intermediate-Level Radioactive Wastes) aims at the implantation of a National Repository for disposal of low and intermediate-level of radiation wastes. This Project has some aspects that are unique in the Brazilian context, especially referring to the time between its construction and the end of its institutional period. This time is about 360 years, when the area will be released for unrestricted uses. It means that the Repository must be safe and secure for more than three hundred years, which is longer than half of the whole of Brazilian history. This aspect is very new for the Brazilian people, bringing a new dimension to public acceptance. Another point is this will be the first repository in South America, bringing a real challenge for the continent. The current status of the Project is summarized. (author)

      Full Text Available The aim of this study is to analyze the efficiency of Brazilian football clubs in generating revenues and the reasons behind it. To achieve this goal, we applied quantitative methods including Data Envelopment Analysis and Tobit regression modeling to data on the best clubs from 2012 to 2014, according to the Brazilian Football Confederation ranking. The results allowed for the inference that the largest Brazilian clubs, such as Grêmio (RS, Palmeiras (SP and Vasco (RJ, were not efficient in any period under analysis. Others, such as Guarani (SP and Guaratinguetá (SP, were efficient in all of years under consideration. With the Tobit regression model, we were able to determine that winning titles and the elite status of a given club are decisive factors in achieving efficiency. Included among the strategies that allow for greater efficiency in Brazilian clubs are the better utilization of stadiums and club assets, maximization of the financial worth of player popularity, and joining these with titles and a place in the A Series. Finally, the results of this study contribute to the strategic development of the football business, highlighting the positive effects that efficiency yields for clubs, thus supporting the growing body of research on sports management in Brazilian academia.

      2012-03-01

      The article is meant to stimulate debate about the social and historical determinants that shape the construction of public mental health policy within the context of the Brazilian family. Current policies have emphasized the family as a strategic target of initiatives aimed at social transformation, with the intervention of different actors, including psychologists. An examination of some ideas from the field of mental hygiene suggests that this discourse is nothing new in the history of Brazilian health. While today's times, families, and professionals are different, the search for a solution to the so-called crisis of society still focuses on the individual. The family, as the expression of this individual, has been called upon to assume responsibilities that push society towards 'order' and 'progress' for the Nation.

      Ribeiro, Edilza Maria

      2004-01-01

      This study presents the scenario that favored the inclusion of the family as a care focus in public policies. The strategies to interrupt the impoverishment and vulnerability of families in the XXth century occur in a different form, according to different "welfare states" in capitalist societies. However, in view of the welfare state crisis and the increasing costs of public and private services and privates, at least a partial family solution is required in terms of reducing its dependency. The Family Health Program (PSF) put the family on the Brazilian social policy agenda in 1994, reflecting interests from the neoliberal model as well as from solidary social forces. This inclusion generated different approaches, such as: family/individual; family/home; family/individual/home; family/community; family/social risk; family/family. These approaches, due to the lack of a mutual dialogue, end up composing an insufficiently identified picture, thus turning care more difficult. The conditions indicated here should be examined as a way of giving a true chance to the family

      Injury is a leading cause of death for infants and children. Teen mothering has been shown to put children at increased risk of injury. The mothers of teen parents often play a predominant role in the lives and caregiving of the children born to their children. This article presents the findings of three focus groups conducted with 21 mothers of teen parents. Grounded theory methodology was used to explore family dynamics and how they relate to injury prevention beliefs and practices regarding infants and children. Our findings revealed the difficulty mothers of teen parents and the teens themselves have in adjusting to the knowledge of the pregnancy. Unique barriers to injury prevention were also uncovered. Our findings provide evidence for the need of a multigenerational approach to programs aimed at improving the safety and well-being of children in this context. Copyright © 2014 Elsevier Ltd.

Ecological study, in which 2,612 police reports registered in Police Stations were analyzed. An instrument was used to obtain data from the victim, the aggressor and the type of violence. Psychological abuse predominated and most cases occurred in the older adults own home. In the cities of Ribeirão Preto and João Pessoa, the older adults presented similar rates for both gender. Regarding the standardized rates, in João Pessoa, there was a rise of this type of abuse in the two first years, and later there was a certain stability. In the city of Teresina, there was an increase, also observed in the city of Ribeirão Preto in the three first years, followed by a decrease. Older adults abuse is a cultural phenomenon difficult to be reported by them, since it occurs in the family context.

      This study evaluated the indoor air quality in Brazilian universities by comparing thirty air-conditioned (AC) (n = 15) and naturally ventilated (NV) (n = 15) classrooms. The parameters of interest were indoor carbon dioxide (CO2), temperature, relative humidity (RH), wind speed, viable mold, and airborne dust levels. The NV rooms had larger concentration of mold than the AC rooms (1001.30 ± 125.16 and 367.00 ± 88.13 cfu/m3, respectively). The average indoor airborne dust concentration exceeded the Brazilian standards (indoor air quality in Brazilian university classrooms affects the health of students. Therefore, indoor air pollution needs to be considered as an important public health problem.

      Familial risks of depression have been assessed in small case-control studies, usually based on reported, but not medically verified, depressions in family members; thus the degree of familial clustering of these diseases remains to be established. The Multigeneration Register, in which all men and women born in Sweden from 1932 onward are registered together with their parents, was linked to hospital admission data. Standardized incidence ratios (SIRs) were calculated as the ratio of the observed to the expected number of cases in men and women with mothers or fathers affected by depression, compared with men and women whose mothers or fathers were not affected by depression. A total of respectively 60,477 and 79,969 depressions were recorded in offspring and parents. In 6.44% of all families, an offspring and a parent were affected, giving a population-attributable proportion of 4.04% and a familial SIR of 2.68. The parental transmission of depression was similar for both men and women (2.72 and 2.66). This study has provided the first data on age-specific familial clustering of depressions, based on medically confirmed records. The risks were so high that hereditary factors were considered to be likely to contribute to depression, possibly modified by environmental factors. Age-specific risk tables would be helpful for clinical counseling.

      Brazil is one of the major contributors to land-use change emissions, mostly driven by agricultural expansion for food, feed, and bioenergy feedstock. Policies to avoid deforestation related to private commitments, economic incentives, and other support schemes are expected to improve the effectiveness of current command and control mechanisms increasingly. However, until recently, land tenure was unknown for much of the Brazilian territory, which has undermined the governance of native vegetation and challenged support and incentive mechanisms for avoiding deforestation. We assess the total extent of public governance mechanisms protecting aboveground carbon (AGC) stocks. We constructed a land tenure dataset for the entire nation and modeled the effects and uncertainties of major land-use acts on protecting AGC stocks. Roughly 70% of the AGC stock in Brazil is estimated to be under legal protection, and an additional 20% is expected to be protected after areas in the Amazon with currently undesignated land undergo a tenure regularization. About 30% of the AGC stock is on private land, of which roughly two-thirds are protected. The Cerrado, Amazon, and Caatinga biomes hold about 40%, 30%, and 20% of the unprotected AGC, respectively. Effective conservation of protected and unprotected carbon will depend on successful implementation of the Forest Act, and regularization of land tenure in the Amazon. Policy development that prioritizes unprotected AGC stocks is warranted to promote conservation of native vegetation beyond the legal requirements. However, different biomes and land tenure structures may require different policy settings considering local and regional specifics. Finally, the fate of current AGC stocks relies upon effective implementation of command and control mechanisms, considering that unprotected AGC in native vegetation on private land only accounts for 6.5% of the total AGC stock. © 2017 John Wiley & Sons Ltd.

      Full Text Available There are few family owned businesses that survive to the next generation. In general, 30% of these businesses are passed on to second generation families and less than 15% survive to third generation families. There has been little research done on third generation family businesses. Therefore the main purpose of this paper is to identify the principal difficulties of passing on managerial skills to the third generation owners. This study uses a case study of a Brazilian family organization composed of twelve enterprises. The instrument to collect data was an individually guided recorded interview with all of the family managers (1ª, 2ª e 3ª generation. The technique applied, was suggested for Miles & Huberman (1994 to group the data in analytical categories to facilitate the analyzed speeches contained in the 49 blocks of responses. As a result, the transition the business to the third generation owners has been strongly associated with the relation between family and business by the following factors: a the succession process influenced by emotional and family values; b conflicts, rivalries and divergences of strategic visions and business goals between the family generations; c lack of professional criteria to hire relatives; and d fragility of communication and consequent asymmetry of information among the family members.

      2010-02-01

      Full Text Available This article is about isolation, contact, and relations between two Amazonian indigenous peoples: the Matis and the Korubo. Both groups, of the Panoan linguistic family, live in the Vale do Javari Indigenous Land, in the state of Amazonas, Brazil. The Matis were contacted by the Funai (the Brazilian agency for indigenous affairs in 1976, and they worked as intermediaries helping the Brazilian government to make contact with the Korubo in 1996. Since then, the Matis have been the main translators and mediators between the Korubo and the rest of the world (indigenous and non-indigenous. Based on my investigation, I propose to classify “isolation” in different ways and to relate the Matis’ own narratives about their contact with their neighbors the Korubo in order to approximate a native conception of what “isolation” and “isolated peoples” mean—if they mean anything at all.

      Coffee is one of the leading commodities in tropical America. Although plantations are usually established under a canopy of trees in most producing countries in the region, Brazilian coffee is mostly produced under full sun conditions. Such simple, single-crop agroecosystems with intensive agrochemical inputs often suffer with pests like mites. Predatory mites of the family Phytoseiidae are the main natural enemies associated with pest mites in the field. However, these beneficial arthropods struggle to survive in intensive agroecosystems such as coffee monocultures due to unfavorable microclimatic conditions, widespread pesticide use, and lack of alternative food (pollen, nectar). Conservation biological control uses a range of management strategies to sustain and enhance populations of indigenous natural enemies such as predatory mites. We discuss here conservation biological control as a strategy to improve biological control of pest mites by native predatory mites in Brazilian coffee monocultures as well as some related patents.

      1994-01-01

      We have determined the beta-globin cluster haplotypes for 80 Indians from four Brazilian Amazon tribes: Kayapó, Wayampí, Wayana-Apalaí, and Arára. The results are analyzed together with 20 Yanomámi previously studied. From 2 to 4 different haplotypes were identified for each tribe, and 7 of the possible 32 haplotypes were found in a sample of 172 chromosomes for which the beta haplotypes were directly determined or derived from family studies. The haplotype distribution does not differ significantly among the five populations. The two most common haplotypes in all tribes were haplotypes 2 and 6, with average frequencies of 0.843 and 0.122, respectively. The genetic affinities between Brazilian Indians and other human populations were evaluated by estimates of genetic distance based on haplotype data. The lowest values were observed in relation to Asians, especially Chinese, Polynesians, and Micronesians.

    14. Jamaican families.

      2003-01-01

      The study of the family in the Caribbean originated with European scholars who assumed the universality of the patriarchal nuclear family and the primacy of this structure to the healthy functioning of society. Matrifocal Caribbean families thus were seen as chaotic and disorganized and inadequate to perform the essential tasks of the social system. This article provides a more current discussion of the Jamaican family. It argues that its structure is the result of the agency and adaptation of its members and not the root cause of the increasing marginalization of peoples in the developing world. The article focuses on families living in poverty and how the family structure supports essential family functions, adaptations, and survival.

      Full Text Available The purpose of this study is to identify and prioritise the various success factors linked to the sustainability of large and medium sized family businesses (FB in the United Arab Emirates (UAE. A well-researched methodology was used for the synthesis of priorities and the measurement of consistencies. The analytic hierarchy process (AHP model was developed with seven criteria and 15 sub-criteria gleaned from prior research. Data were collected using an interview-based survey conducted on twelve medium and large sized family firms in the UAE. The data collected were interpreted and a priority vector was assigned. The findings show that large family businesses in the UAE are aware of transition failure and have long-term planning for their future generations in place; however, they need to give more importance to family values and family capital. On the other hand, medium sized family businesses are less aware of transition failure and have limited long-term planning; they are more concerned with short-term returns. Therefore, they need to create and give more importance to succession planning, strategic planning and corporate governance to ensure their business longevity. The study highlights multi-generation family business sustainability, and identifies the major determinants that the family members and business leaders need to consider for their business continuity and survival. The model can be utilized by academics in family business sustainability studies. The findings interpreted can help policy makers and related associations develop various policies based on the specific factors found to run the family businesses in a sustainable manner. The research model had limited dimensions and the findings cannot be generalized. This study is the first to study the determinants of family business sustainability in the context of the UAE using the AHP model.

      The aim of the present study was to provide new spirometry reference equations in a sample of the Brazilian population for the following parameters: forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), FEV1/FVC ratio, peak of expiratory flow (PEF), forced expiratory flow at 50% (FEF50%), 75% average vital capacity (FEF25-75%), and average forced expiratory flow time (FEFT). This was a prospective study using results from chest radiographs, electrocardiograms, and questionnaires to investigate the participants' respiratory symptoms, sedentarism, and comorbidities (Charlson comorbidity index). From December 2010 to July 2014, individuals were randomly selected from various locations in the state of Rio de Janeiro. All individuals were examined by a single technician in the morning at the laboratory, and performed the spirometry with the same spirometer. Spirometry values were tabulated for the creation of three equation models: linear regression, logarithmic regression, and logarithms through a method that incorporates the lambda, median, and coefficient of variation (LMS method). Initially, 7003 individuals from both genders were contacted, and 454 were recruited. The data from the new equations were compared with one Brazilian and eight international equations, resulting in a high correlation (r>0.9). The values derived from the LMS method and linear regression were very similar (P>0.5), and both could be used to acquire the reference values for Brazilian spirometry. Data derived from the equations of this study were different from the current Brazilian equation, which could be justified by the different method used.

      2001-01-01

      Full Text Available An analysis of Brazilian federal expenditures in science and technology is presented is this study. The 1990-1999 data were compiled from records provided by two federal agencies (MCT and CNPq responsible for managing most of the national budget related to these activities. The results indicate that the federal investments in Brazilian science and technology stagnated during the last decade (US$ 2.32 billion in 1990, US$ 2.39 billion in 1996, and US$ 2.36 billion in 1999. In contrast, a great increase in private investments in research was acknowledged both by industry and by the government during the same period, from US$ 2.12 to US$ 4.64 billion. However, this investment did not result in an increase in invention patents granted to residents (492 in 1990 and only 232 in 1997 or in a reduction of patent costs. Despite this unfavorable scenario, the number of graduate programs in the country has increased two-fold in the last decade and the contribution of Brazilians to the database of the Institute for Scientific Information has increased 4.7-fold from 1990 (2,725 scientific publications to 2000 (12,686 scientific publications. Unstable federal resources for science, together with the poor returns of private resources in terms of developing new technologies, may jeopardize the future of Brazilian technological development.

      2016-06-01

      Full Text Available ABSTRACT The present study aims to study earnings management in a significant sample of 123 banks in the Brazilian market between 2001 and 2012. Given the important role that banks play in a country's economy, it is important to understand that there are discretionary factors involved in the reporting of a financial institution's profitability. Credit provisioning guidelines for Brazilian financial institutions are described in Resolution 2682/99 of the National Monetary Council (Conselho Monetário Nacional. Because of the discretion allowed in this resolution, loan loss provision is used as instrument of earnings management, which is not an illegal practice, but this behavior does affect the risk perception of agents and analysts, and they should be aware of it and understand it. We found that credit provisioning is used as an earnings management mechanism to smooth the net income of Brazilian financial institutions. Brazilian banks tend to avoid not only negative net income pre-loan loss provisions and taxes, but also negative net income pre-loan loss provisions and taxes in relation to the previous period. Contrary to the previous studies, it is not clear if banks avoid lower net income pre-loan loss provisions and taxes than a given peer group.

      In 2005, Brazil addressed the environmental challenges posed by ballast water through a unilateral regulation, called the Maritime Standard N° 20 (NORMAM-20), applied to all shipping in her waters. This world-leading decision was the culmination of a process that started during the 1990‧s. Here, we summarize how these ballast water regulations were brought in and adopted and present the findings of 10 years of enforcement (2005-2015) in 39 ports along the Brazilian coast. We show that compliance with the Brazilian standard has increased significantly since the regulations were implemented (p < 0.001). After five years of implementation, non-compliance decreased probably reflecting an increase in awareness of the Brazilian Standard and a shift in the shipping industry commitment to minimize and control the spread of invasive species through ballast water. The Brazilian experience shows that very high levels (97%) of compliance with ballast water management regulations can be made to work in a region of global importance to the maritime industry. In the last decade, the rules governing ballast water in Brazil have evolved to address the demands from the maritime community and to provide updates such as imminent requirements for the use of ballast water management systems on board ships. These regulations are rarely cited when ballast water regulations are discussed internationally, yet there is much to learn from the proactive approach taken by Brazil such as what is feasible and enforceable.

      Full Text Available The prevalence of obesity, pre-diabetes, and type 2 diabetes (T2D is increasing worldwide, especially in the developing nations of South America. Brazil has experienced an exponential increase in the prevalence of these chronic non-communicable diseases. The rising prevalence is probably due to changing eating patterns, sedentary living, and a progressive aging of the population. These trends and their underlying causes carry untoward consequences for all Brazilians and the future of Brazilian public health and the healthcare system. Lifestyle changes that include healthy eating (nutrition therapy and regular physical activity (structured exercise represent efficient inexpensive measures to prevent and/or treat the aforementioned disorders and are recommended for all afflicted patients. Regrettably, the implementation of lifestyle changes is fraught with clinical and personal challenges in real life. The transcultural Diabetes Nutrition Algorithm (tDNA is a therapeutic tool intended to foster implementation of lifestyle recommendations and to improve disease-related outcomes in common clinical settings. It is evidence-based and amenable to cultural adaptation. The Brazilian Diabetes Association, Society of Cardiology and Ministry of Health guidelines for nutrition therapy and physical exercise were considered for the Brazilian adaptation. The resultant tDNA-Brazil and its underlying recommendations are presented and explained.

      2002-01-01

      Full Text Available This paper uses several produceres to date and analyse the Brazilian business and growth cycles. In particular, a Markov switching model is fitted to quarterly and annual real production data. The smoothed probabilities of the Markov states are used as predictive rules to define different phases of cyclical fluctuations of real Brazilian production. The results are compared with different non-parametric rules. All methods implemented yield similar dating and reveal asymmetries across the different states of the Brazilian business and growth cycles, in which slowdowns and recessions are short and abrupt, while high growth phases and expansions are longer and less steep. The resulting dating of the Brazilian economic cycles can be used as a reference point for construction and evaluation of the predictive performance of coincident, leading, or lagging indicators of economic activity. In addition, the filtered probabilities obtained from the Markov switching model allow early recognition of the transition to a new business cycle phase, wich can be used, for example, for evaluation of the adequate strength and timing of countercyclical policies, for reassessment of projected sales or profits by businesses and investors, or for monitoring of inflation pressures.

      Brazil has four research reactors (RR) in operation: IEA-R1, a 5 MW pool type RR; IPR-R1, a 100 kW TRIGA type RR; ARGONAUTA, a 500 W Argonaut type RR, and IPEN/MB-01, a 100 W critical facility. The first three were constructed in the 50's and 60's, for teaching, training, and nuclear research, and for many years they were the basic infrastructure for the Brazilian nuclear developing program. The last, IPEN/MB-01, is the result of a national project developed specifically for qualification of reactor physics codes. Considering the relative low power of Brazilian research reactors, with exception of IEAR1, none of the other reactors are feasible for radioisotope production, and even IEA-R1 has a limited capacity. As a consequence, since long ago, 100% of the Mo-99 needed to attend Brazilian nuclear medicine services has been imported. Because of the high dependence on external supply, the international Moly-99 supply crisis that occurred in 2008/2009 affected significantly Brazilian nuclear medicine services, and as presented in previous IAEA events, in 2010 Brazilian government formalized the decision to build a new research reactor. The new reactor named RMB (Brazilian Multipurpose Reactor) will be a 30 MW open pool type reactor, using low enriched uranium fuel. The facility will be part of a new nuclear research centre, to be built about 100 kilometres from Sao Paulo city, in the southern part of Brazil. The new nuclear research centre will have several facilities, to use thermal and cold neutron beams; to produce radioisotopes; to perform neutron activation analysis; and to perform irradiations tests of materials and fuels of interest for the Brazilian nuclear program.

      The H19/IGF2 imprinted loci have attracted recent attention because of their role in cellular differentiation and proliferation, heritable gene regulation, and in utero or early postnatal growth and development. Expression from the imprinted H19/IGF2 locus involves a complex interplay of 3 means of epigenetic regulation: proper establishment of DNA methylation, promoter occupancy of CTCF, and expression of microRNA-675. We have demonstrated previously in a multigenerational rat model of intrauterine growth restriction the epigenetic heritability of adult metabolic syndrome in a F2 generation. We have further demonstrated abrogation of the F2 adult metabolic syndrome phenotype with essential nutrient supplementation of intermediates along the 1-carbon pathway and shown that alterations in the metabolome precede the adult onset of metabolic syndrome. The upstream molecular and epigenomic mediators underlying these observations, however, have yet to be elucidated fully. In the current study, we sought to characterize the impact of the intrauterine growth-restricted lineage and essential nutrient supplementation on both levels and molecular mediators of H19 and IGF2 gene expression in the F2 generation. F2 intrauterine growth-restricted and sham lineages were obtained by exposing P1 (grandmaternal) pregnant dams to bilateral uterine artery ligation or sham surgery at gestational day 19.5. F1 pups were allocated to the essential nutrient supplemented or control diet at postnatal day 21, and bred at 6-7 weeks of age. Hepatic tissues from the resultant F2 offspring at birth and at weaning (day 21) were obtained. Bisulfite modification and sequencing was employed for methylation analysis. H19 and IGF2 expression was measured by quantitative polymerase chain reaction. Promoter occupancy was quantified by the use of chromatin immunoprecipitation, or ChIP, against CTCF insulator proteins. Growth-restricted F2 on control diet demonstrated significant down-regulation in H19

      Several studies in mammals focused on the maternal programming of the metabolism by epigenetic mechanisms, while currently, the consequences of a maternal dietary treatment on the offspring performance of farm animals are of particular interest for commercial purpose. In the present study, we investigated if the zootechnical performance of the progeny was altered by a maternal dietary treatment, being a lower dietary crude protein (CP) of the grandparent and/or parent generation. The multigenerational effects of a reduced maternal CP content were investigated by reducing the dietary CP level by 25% in rearing and laying diets of pure line A breeders. The F0 generation breeders were fed either control (C) or reduced balanced protein (RP) diets. The F1 breeder generation was constructed by dividing the F0 female progeny again over a C or RP diet, resulting in 4 dietary treatments in the F1 generation: C/C, C/RP, RP/C, and RP/RP (letters indicating the diets in, respectively, F0 and F1 generations). The offspring performance was evaluated by a zootechnical and nitrogen retention trial on C and low-protein (LP) broiler diets. For the C broiler diet, the C/RP and RP/RP offspring were characterized by a higher BW from d 35 until d 42 compared to the C/C progeny, whereas the RP/C offspring had an intermediate BW that did not differ from the other groups. A tendency (P = 0.067) towards a better nitrogen retention was observed for the offspring of breeders that received the RP diets in F0 and/or F1 generation compared to the C/C progeny. For the LP broiler diet, the C/RP (P = 0.021) and RP/C (P = 0.001) offspring had a higher BW compared to the C/C progeny during the entire grow-out period. In addition, the C/RP offspring were characterized by a lower FCR from d 28 onwards (P = 0.021). In conclusion, dietary treatments imposed on mother hens can have direct effects on the next generation, as well as indirect effects on multiple generations.

Although pesticides used in agriculture have been frequently mentioned as an additional force driving the selection of resistance, only a few studies were dedicated to validate this hypothesis and characterise the underlying mechanisms. While insecticide resistance is rising dramatically in Africa, deciphering how agriculture affects resistance is crucial for improving resistance management strategies. In this context, the multigenerational effect of agricultural pollutants on the selection of insecticide resistance was examined in Anopheles gambiae. An urban Tanzanian An. gambiae population displaying a low resistance level was used as a parental strain for a selection experiment across 20 generations. At each generation larvae were selected with a mixture containing pesticides and herbicides classically used in agriculture in Africa. The resistance levels of adults to deltamethrin, DDT and bendiocarb were compared between the selected and non-selected strains across the selection process together with the frequency of kdr mutations. A microarray approach was used for pinpointing transcription level variations selected by the agricultural pesticide mixture at the adult stage. A gradual increase of adult resistance to all insecticides was observed across the selection process. The frequency of the L1014S kdr mutation rose from 1.6% to 12.5% after 20 generations of selection. Microarray analysis identified 90 transcripts over-transcribed in the selected strain as compared to the parental and the non-selected strains. Genes encoding cuticle proteins, detoxification enzymes, proteins linked to neurotransmitter activity and transcription regulators were mainly affected. RT-qPCR transcription profiling of candidate genes across multiple generations supported their link with insecticide resistance. This study confirms the potency of agriculture in selecting

      A microplate assay and a thin-layer chromatography (TLC) "in situ" assay based on the Ellman assay was used to screen for acetylcholinesterase inhibitors from ethyl acetate and methanol extracts of Brazilian medicinal plants of families that, according to the literature, have traditional uses that might be connected with acetylcholinesterase inhibition. Eighteen species belonging to Convolvulaceae, Crassulaceae, Euphorbiaceae, Leguminosae, Malvaceae, Moraceae, Nyctaginaceae and Rutaceae families were tested. The most active plants were Ipomoea asarifolia (IC50 = 0.12 mg/mL), Jatropha curcas (IC50 = 0.25 mg/mL), Jatropha gossypiifolia (IC50 = 0.05 mg/mL), Kalanchoe brasiliensis (IC50 = 0.16 mg/mL) and Senna alata (IC50 = 0.08 mg/mL). The most promising extracts were the Jatropha gossypiifolia and Senna alata species assuming there were compounds with a similar activity to galanthamine, which should contain about 1% of an active compound, or if present at lower levels even more active compounds than galanthamine (IC50 = 0.37 x 10-3 mg/mL) should be present.

      Etiological theory and prior research with small or selected samples suggest that interpersonal violence clusters in families. However, the strength and pattern of this aggregation remains mostly unknown. We investigated all convictions for violent crime in Sweden 1973-2004 among more than 12.5 million individuals in the nationwide Multi-Generation Register, and compared rates of violent convictions among relatives of violent individuals with relatives of matched, non-violent controls, using a nested case-control design. We found strong familial aggregation of interpersonal violence among first-degree relatives [e.g. odds ratio (OR)sibling 4.3, 95% confidence interval (CI) 4.2-4.3], lower for more distant relatives (e.g. OR cousin 1.9, 95% CI 1.9-1.9). Risk patterns across biological and adoptive relations provided evidence for both genetic and environmental influences on the development of violent behavior. Familial risks were stronger among women, in higher socio-economic strata, and for early onset interpersonal violence. There were crime-specific effects (e.g. OR sibling for arson 22.4, 95% CI 12.2-41.2), suggesting both general and subtype-specific familial risk factors for violent behavior. The observed familiality should be accounted for in criminological research, applied violence risk assessment, and prevention efforts.

      In recent years, sociological research investigating grandparent effects in three-generation social mobility has proliferated, mostly focusing on the question of whether grandparents have a direct effect on their grandchildren's social attainment. This study hypothesizes that prior research has overlooked family structure as an important factor that moderates grandparents' direct effects. Capitalizing on a counterfactual causal framework and multigenerational data from the Panel Study of Income Dynamics, this study examines the direct effect of grandparents' years of education on grandchildren's years of educational attainment and heterogeneity in the effects associated with family structure. The results show that for both African Americans and whites, grandparent effects are the strongest for grandchildren who grew up in two-parent families, followed by those in single-parent families with divorced parents. The weakest effects were marked in single-parent families with unmarried parents. These findings suggest that the increasing diversity of family forms has led to diverging social mobility trajectories for families across generations.

      Hypertension clusters in families. However, no nationwide study has investigated the family history as a predictor of hospitalization for hypertension, which was the purpose of this study. The study is a nationwide follow-up study. Swedish Multigeneration Register data for individuals aged 0-76 years were linked to Hospital Discharge Register data for 1964-2008. Standardized incidence ratios (SIRs) were calculated for individuals whose relatives were hospitalized with a main diagnosis of hypertension compared with those whose relatives were not. The total number of patients hospitalized with hypertension was 37,686. The familial SIR was 2.18 for individuals with one affected sibling, 44.83 for individuals with two affected siblings and 57.18 for individuals with three or more affected siblings. The SIR was 1.95 for parents with one affected child, 3.73 for parents with two affected children and 9.22 for parents with three or more affected children. The familial SIR among offspring was 1.84 for those with one affected parent and 3.62 for those with two affected parents. The familial risk for hospitalization with hypertension among offspring aged less than 30 years was 2.50 and 1.57 in those aged more than 60 years. Familial risks were similar for men and women. Spouses had low overall familial risks (SIR=1.2). Hospitalization for hypertension clusters in families. Very high risks were observed in families with multiple affected siblings, though the parent-offspring transmission was lower, suggesting the segregation of recessive or interacting susceptibility genes. The low familial risk in spouses suggests a minor nongenetic contribution.

      In the 80's the Brazilian economy underwent one of the most severe crises of its history, resulting in the stagnation of the gross national product and inflation rates such as never previously reported. Despite this unfavorable scenario social indicators have presented a positive evolution. This work shows that although the Brazilian family has adopted the over-use of the family work force as a strategy for facing this crisis on the work market, the evolution of both income and poverty in that period were poor. The increase of expenses and the transformation of the forms of implementation of public policy in the health and nutrition areas are shown to be decisive factors in the performance of social indicators.

      Familial clustering of chronic obstructive pulmonary disease (COPD) is well established, but the familial risk of COPD has not been determined among adoptees. The aim was to determine whether the familial transmission of COPD is related to disease in biological and/or adoptive parents. Historic cohort study. 80,214 (50% females). The Swedish Multi-Generation Register was used to follow all Swedish-born adoptees born in 1932-2004 (n=80,214) between 1 January 1964 and 31 December 2010 for COPD (n=1978). The risk of COPD was estimated in adoptees with at least one biological parent with COPD but no adoptive parent with COPD (n=162) compared with adoptees without a biological or adoptive parent with COPD. The risk of COPD was also determined in adoptees with at least one adoptive parent but no biological parent with COPD (n=110), and in adoptees with both affected biological and adoptive parents (n=162). COPD in adoptees. Adoptees with COPD in at least one biological parent but no adoptive parent were more likely to have COPD than adoptees without a biological or adoptive parent with COPD (standardised incidence ratio, SIR=1.98 (95% CI 1.69 to 2.31)). The familial SIR for adoptees with both a biological parent and an adoptive parent with COPD was 1.68 (95% CI 1.39 to 2.00). Adoptees with at least one adoptive parent with COPD but no biological parent with COPD were not at an increased risk of COPD (SIR=1.12 (95% CI 0.92 to 1.35)). The findings of the study show that the familial transmission of COPD is associated with COPD in biological but not adoptive parents, suggesting that genetic or early life factors are important in the familial transmission of COPD.

      Full Text Available This article's main goal is to analyze how the evolution of organizational culture can impact business performance. A theoretical framework was developed based on a review of the literature relating to organizational culture and family business succession management models. A single case study methodology was adopted based on primary and secondary data obtained through documentary research, participant observation and interviews at Guapo Loco, a Brazilian chain of Mexican restaurants / fun bars, which is a family company and was founded in Rio de Janeiro in 1996. We focused on its leader's trajectory and its implications for the life cycle of the family business, the founder¿s dream and vision, succession and cultural management difficulties. We conclude that it is possible for an organization to become trapped by its cultural formation. We will see that as it reaches maturity, the organizational, family and shareholder dimensions need to adapt in a similar fashion. At this stage, the organizational culture may become dysfunctional, jeopardizing the organization's survival.

      We present distribution data of all Alopoglossidae and Gymnophthalmidae lizards known from the Brazilian Amazonia, totaling 54 species-level taxa, belonging to 17 genera and two families. This represents 22 more species-level taxa than previously reported. Data were based on 17,431 specimens deposited in three North American and eight Brazilian museums, including the main collections harboring Amazonian material. Most species (~80%) are endemic to Amazonia; non-endemic species are mainly associated with open vegetation (savanna) enclaves or open dry (semideciduous) forest in Amazonia, with a few exceptions. As a whole, seven taxa (including one species complex) are widespread in Amazonia, six are restricted to eastern Amazonia, seven to western Amazonia, two to southwestern Amazonia, 11 to southern Amazonia, 11 to northern Amazonia (either in part of it or widespread in the Guiana region), and six to the southern peripheral portion of Amazonia. Besides, four species present unique distributions. Considering this study and the other three catalogues of distribution of lizards already published, the total number of lizard species from Brazilian Amazonia increased from 97 to 142 species-level tava. It represents an increase of 45 species from the region since the last revision.

      Inadequate functional health literacy is a common problem in immigrant populations. The aim of this study was to investigate the association between oral (dental) health literacy (OHL) and participation in oral health care among Brazilian immigrants in Toronto, Ontario, Canada. The study used a cross-sectional design and a convenience sample of 101 Brazilian immigrants selected through the snowball sampling technique. Data were analyzed using descriptive statistics and logistic regression modeling. Most of the sample had adequate OHL (83.1 %). Inadequate/marginal OHL was associated with not visiting a dentist in the preceding year (OR = 3.61; p = 0.04), not having a dentist as the primary source of dental information (OR = 5.55; p < 0.01), and not participating in shared dental treatment decision making (OR = 1.06; p = 0.05; OHL as a continuous variable) in multivariate logistic regressions controlling for covariates. A low average annual family income was associated with two indicators of poor participation in oral health care (i.e., not having visited a dentist in the previous year, and not having a dentist as regular source of dental information). Limited OHL was linked to lower participation in the oral health care system and with barriers to using dental services among a sample of Brazilian immigrants. More effective knowledge transfer will be required to help specific groups of immigrants to better navigate the Canadian dental care system.

    1. Labor and Employment in Brazilian Northeastern Agriculture: a look at the 2004-2014 period

      Otavio Valentim Balsadi

      Full Text Available Abstract: The labor market in the Brazilian Northeastern agriculture is characterized by many forms of occupation, ranging from the salaried work to the various forms of family work. In a heterogeneous and diverse agriculture, there is a complex labor market, with changes in recent times. Therefore, it is necessary to keep a watchful eye on important structural features. As a result, this paper aims to analyze the main aspects related to work and employment relations in the Brazilian Northeastern agriculture in the 2004-2014 period. The sources of information are special tabulations from the National Survey by Household Sample (PNAD, conducted by the Brazilian Institute of Geography and Statistics (IBGE. The results pointed to a continuing decline in Northeastern PEA (Economically Active Population occupied in agriculture, partially offset by the growth of Northeastern rural residents occupied in non-agricultural activities, in addition to the people occupied in self-consumption production. Women and young people were the ones who mostly left the agricultural activities, reinforcing the “ageing” process of the occupied PEA. The crops with the largest reduction in the occupied in agricultural PEA were: cassava, rice, coffee, banana, sugarcane, cocoa, vegetables and fruits. On the other hand, the number of occupied people increased in: corn and grape cultivation, services for agriculture, swine and poultry farming and integrated agricultural and livestock production systems. An increase in schooling of the occupied PEA was registered, though it is still below the national average.

      To review and discuss childhood and adolescence vulnerabilities, as well as Brazilian public policies of intervention. A narrative review was performed, considering studies published between 1990 and 2012, found in the Virtual Health Library databases (Biblioteca Virtual em Saúde - BVS). A combination of the following descriptors was used in the search strategy: "Adolescent Health", "Child Health", "Health Public Politics" and "Vulnerability". In addition, Brazilian official documents, the Statute of the Child and the Adolescent, Guardianship Council, Bolsa Família and Saúde na Escola Programs were evaluated. The results were divided into five categories of analysis: Vulnerability of Children and Adolescents in Brazil, Public Politics of Intervention to Risk Factors in Childhood and Adolescence, the Statute of the Child and the Adolescent and Guardianship Council, Bolsa Família Program and Saúde na Escola Program. The studies show that children and adolescents are vulnerable to environmental and social situations. Vulnerabilities are exhibited in daily violence within families and schools, which results in the premature entrance of children and adolescents in the work environment and/or in the drug traffic. To deal with these problems, the Brazilian Government established the Statute of the Child and the Adolescent as well as social programs. Literature exposes the risks experienced by children and adolescents in Brazil. In the other hand, a Government endeavor was identified to eliminate or minimize the suffering of those in vulnerable situations through public policies targeted to this population group.

      Full Text Available The primary goal of this paper is to comprehend the fundamental organizational differences between Brazilian franchise chains that only operate in the home market and Brazilian franchise chains that operate internationally. The sample chosen for this study comprehends 96 Brazilian franchises operating in the home market and 67 franchises with international operations; logistic regression was used to analyze data obtained from these sources. Our findings suggest that the development of a brand in international operations can be strategic for certain Brazilian franchise chains; this seems to be, however, a scarce resource for many franchises and it could be developed through international operations. With regard to the fees charged, the outcomes demonstrate that Brazilian franchises with international operations tend to charge lower fees from its franchisees to install new units. Regarding the monitoring and control of franchises, there is evidence that the monitoring capability is one of the determining factors in the development of Brazilian franchises international operations.

      The study of calcareous nanofossils occurring in the deposits on the Brazilian continental margin began in the late 1960s, undertaken solely by PETROBRAS. Instead of presenting an academic outlook, the purpose of these investigations is first to formulate a biostratigraphic framework to apply to oil well samples. The initial result was the first zoning for the Brazilian continental margin, which considered the deposits formed between the Aptian and Miocene series. Since the 1960s to date, many papers have been written either with details of that original zoning or applying nanofossil biostratigraphy to solve stratigraphic problems. Regardless of all the papers and studies undertaken, little attention has been paid to the Quaternary, since these deposits are normally of no interest to petroleum geology stricto sensu, especially in a large part of the Brazilian margin. On the other hand, there are a few articles and some Master's dissertations and PhD theses that were written and/or are in progress in Brazilian universities. On the other hand, elsewhere in the world, Quaternary nanofossils have been thoroughly investigated in terms of biostratigraphy and paleoceanography. It is, therefore, very clear that there is a gap between what is being done elsewhere in the world and what has been done in Brazil. In fact, this gap is not larger simply because of a few researchers in Brazilian universities who are studying this topic. The intention of this paper is to contribute toward a richer study of Quaternary nanofossils. It, therefore, contains illustrations and taxonomic descriptions of many species observed in the younger strata of the Brazilian margin basins. This article not only aspires to portray and disseminate the potential of nanofossils for the marine Quaternary study but is also an invitation to students (under and post-graduates) and university researchers - an invitation to learn a little more about the subject and spend some time studying these real gems

    7. Short-Term and Long-Term Educational Mobility of Families: A Two-Sex Approach.

      Song, Xi; Mare, Robert D

      2017-02-01

      We use a multigenerational perspective to investigate how families reproduce and pass their educational advantages to succeeding generations. Unlike traditional mobility studies that have typically focused on one-sex influences from fathers to sons, we rely on a two-sex approach that accounts for interactions between males and females-the process in which males and females mate and have children with those of similar educational statuses and jointly determine the educational status attainment of their offspring. Using data from the Panel Study of Income Dynamics, we approach this issue from both a short-term and a long-term perspective. For the short term, grandparents' educational attainments have a direct association with grandchildren's education as well as an indirect association that is mediated by parents' education and demographic behaviors. For the long term, initial educational advantages of families may benefit as many as three subsequent generations, but such advantages are later offset by the lower fertility of highly educated persons. Yet, all families eventually achieve the same educational distribution of descendants because of intermarriages between families of high- and low-education origin.

      Full text: The Brazilian research reactors have a limited capacity for radioisotopes production, leading to a high dependence on external supply for radioisotopes used in nuclear medicine. In order to overcome this condition and due to the old age of these research reactors, the Brazilian Nuclear Energy Commission decided, in 2008, to construct a new research reactor. The new reactor named RMB (Brazilian Multipurpose Reactor) will be part of a new nuclear research center, to be built on a site about 100 kilometers from São Paulo city, in the southern part of Brazil. The new nuclear research center will have a 30 MW open pool type research reactor using low enriched uranium fuel, and several associated laboratories in order to produce radioisotopes for medical and industrial use, to use neutron beams in scientific and technological research; to perform neutron activation analysis; and to perform materials and fuels irradiation tests. Regarding the neutron beams use, the RMB design provides thermal and cold neutron beams. From one side of the reactor, the neutron guides will extend to an experimental hall of instruments named Neutron Guide Hall where it will be installed the scattering instruments. In the initial stage of the reactor operation, the intent is to implement two neutron guides for thermal neutrons and another two for cold neutrons. The 2015 SBPMAT symposium has presented the technical overview of the RMB project and its main buildings, structures and components. At this year symposium, the RMB presentation updates some technical information and the development status of the project, discussing the negative results of the Brazilian political and economic crisis to the project development and its future perspectives.

      Full Text Available The aim of the present study was to provide new spirometry reference equations in a sample of the Brazilian population for the following parameters: forced vital capacity (FVC, forced expiratory volume in 1 second (FEV1, FEV1/FVC ratio, peak of expiratory flow (PEF, forced expiratory flow at 50% (FEF50%, 75% average vital capacity (FEF25-75%, and average forced expiratory flow time (FEFT. This was a prospective study using results from chest radiographs, electrocardiograms, and questionnaires to investigate the participants' respiratory symptoms, sedentarism, and comorbidities (Charlson comorbidity index. From December 2010 to July 2014, individuals were randomly selected from various locations in the state of Rio de Janeiro. All individuals were examined by a single technician in the morning at the laboratory, and performed the spirometry with the same spirometer. Spirometry values were tabulated for the creation of three equation models: linear regression, logarithmic regression, and logarithms through a method that incorporates the lambda, median, and coefficient of variation (LMS method. Initially, 7003 individuals from both genders were contacted, and 454 were recruited. The data from the new equations were compared with one Brazilian and eight international equations, resulting in a high correlation (r>0.9. The values derived from the LMS method and linear regression were very similar (P>0.5, and both could be used to acquire the reference values for Brazilian spirometry. Data derived from the equations of this study were different from the current Brazilian equation, which could be justified by the different method used.

      Sexuality education has been valued since the 1960s in medical schools worldwide. Although recent studies reaffirm the importance of incorporating sexuality into medical education, there are data gaps concerning how this happens in Brazil. To understand how Brazilian medical school professors teach sexuality in undergraduate courses. An exploratory, cross-sectional descriptive study was conducted. A total of 207 professors from 110 Brazilian medical schools responded to an online semistructured questionnaire about the characteristics of the sexuality-related topics offered. The main variables assessed were contact hours devoted to sexuality, disciplines in which sexuality topics were taught, sexuality-related course titles, and sexuality-related topics addressed. Questionnaires were tabulated and analyzed using descriptive statistics for frequency distribution. The response rate to the questionnaire was 77.2%. Almost all professors (96.3%) addressed sexuality-related topics mainly in the third and fourth years as clinical disciplines, with a 6-hour load per discipline. Gynecology was the discipline in which sexuality-related topics were most often taught (51.5%), followed by urology (18%) and psychiatry (15%). Sexuality-related topics were addressed mainly in classes on sexually transmitted diseases and AIDS (62.4%) and on the anatomy and physiology of the reproductive system (55.4%). About 25% of the professors reported teaching courses with a sexuality-related title. There was emphasis on the impact of diseases and sexual habits (87.9%) and sexual dysfunction (75.9%). Less than 50% of professors addressed nonnormative sexuality or social aspects of sexuality. The teaching of sexuality in Brazilian medical schools occurred in a nonstandardized and fragmented fashion across several disciplines. The topic was incorporated with an organic and pathological bias, with a weak emphasis on the social aspects of sexuality and the variety of human sexual behaviors. The

      Full Text Available This publication is part of a major study (Thesis. In that thesis it was analyzed the intention of Pronaf's beneficiaries to repay the credit they have received. The Pronaf is a line of credit for small farmers implemented by the Brazilian Federal Government in 1996. Ajzen's Theory of Planned Behavior (1991 was used to evaluate the beneficiaries' intention in paying what they owned. In order to accomplish this evaluation, two studies were conducted. The first one (Preliminary Study focused on the small farmer's beliefs about the program operation. The second (Main Study focused on the measurement of these beliefs. Two beneficiary groups participated of the studies: Group A (agrarian reform settlers and Group B (small farmers. According to Ajzen's model, for the participants of the Group A, the Attitude, the Normative belief (subjective norm component and the Subjective Norm were positive significant predictors of the Intention to repay the credit. For the Group B, the Attitude, Behavioral belief (attitude component, Normative belief (subjective norm component and Control belief (perceived behavioral control component were positive significant predictors of the Intention to repay the credit. The Perceived behavioral control did not influence directly the behavioral Intention, but this variable indirectly predicts the target behavior.

      This article examines some political and economic facts that led to an intensification of austerity measures by the Brazilian government, including ones against the Unified Health System (SUS) and its progressive dismantling. In a country where fundamental human rights were never fully respected, nowadays social and labor rights are under severe attacks. The deepening of the capital crisis and the rise of interest-bearing capital dominance have been causing unemployment, social insecurity growth, and resulting public fund appropriation by the private capital. The Brazilian governments in the 1990s and 2000s have implemented deeper cuts in social policy expenditure, freezing security benefits, privatizing services, and prioritizing the payment of public debt interests. The right wing's project involves the demoralization of not only the Workers' Party but also the left as a whole, so that the adoption of austerity measures could be achieved without popular resistance. It is the duty of the Brazilian left wing to denounce such a project and to provoke firm initiatives to rebuild its bonds with the working class.

      We have performed observations of the sky alongside with the Indians of all Brazilian regions that made it possible localize many indigenous constellations. Some of these constellations are the same as the other South American Indians and Australian aborigines constellations. The scientific community does not have much of this information, which may be lost in one or two generations. In this work, we present a planetary-observatory that we have made in the Park of Science Newton Freire-Maia of Paraná State, in order to popularize the astronomical knowledge of the Brazilian Indians. The planetary consists, essentially, of a sphere of six meters in diameter and a projection cylinder of indigenous constellations. In this planetary we can identify a lot of constellations that we have gotten from the Brazilian Indians; for instance, the four seasonal constellations: the Tapir (spring), the Old Man (summer), the Deer (autumn) and the Rhea (winter). A two-meter height wooden staff that is posted vertically on the horizontal ground similar to a Gnomon and stones aligned with the cardinal points and the soltices directions constitutes the observatory. A stone circle of ten meters in diameter surrounds the staff and the aligned stones. During the day we observe the Sun apparent motions and at night the indigenous constellations. Due to the great community interest in our work, we are designing an itinerant indigenous planetary-observatory to be used in other cities mainly by indigenous and primary schools teachers.

      Full Text Available This study evaluated the indoor air quality in Brazilian universities by comparing thirty air-conditioned (AC (n = 15 and naturally ventilated (NV (n = 15 classrooms. The parameters of interest were indoor carbon dioxide (CO2, temperature, relative humidity (RH, wind speed, viable mold, and airborne dust levels. The NV rooms had larger concentration of mold than the AC rooms (1001.30 ± 125.16 and 367.00 ± 88.13 cfu/m3, respectively. The average indoor airborne dust concentration exceeded the Brazilian standards (<80 µg/m3 in both NV and AC classrooms. The levels of CO2 in the AC rooms were significantly different from the NV rooms (1433.62 ± 252.80 and 520.12 ± 37.25 ppm, respectively. The indoor air quality in Brazilian university classrooms affects the health of students. Therefore, indoor air pollution needs to be considered as an important public health problem.

      Full Text Available This study consists of an intervention using narrative workshops as a device to stimulate the empowerment of women. Ten women, victims of gender violence, took part in a workshop developed by non-governmental organization for African-Brazilian women Maria Mulher, which gives assistance to women living in Vila Cruzeiro do Sul, in the city of Porto Alegre. The main objective of the research was to debate questions related to gender and violence, making use of stories and histories related to the feminine, specifically African-Brazilian stories. Five meetings were held, where the women told and were told stories, took part in group discussions, experiences and rituals. The workshops gave those women a space where they could tell and hear stories, take part in the rituals of the orixás [African-Brazilian deities] of the black culture and tell their personal histories using those experiences. This intervention was an attempt at invoking different subjective experiences, and made it possible to empower the women who took part in the research, contributing for the rescue of the individual and collective memory of this group.

      Even considered not essential for plants, cesium may cycle within forest ecosystems. Taking into account the lack of knowledge on the distribution of this chemical element in Brazilian ecosystems, this work encompasses the unexpected cesium accumulation in native plant leaves from Cerradao, a Brazilian hotspot of world biodiversity. Some trees were Cs accumulators, achieving mass fractions in leaves 700 times higher (up to 12.7 mg kg -1 ) when compared to other Brazilian native tree leaves from the Atlantic Forest. In fact, such trace element accumulation in leaves was not previously noticed for Brazilian ecosystems despite the intra- and inter-species variability observed in Cerrado tree leaves. (author)

      Secondary organic aerosol (SOA) is an important contributor to fine particulate matter (PM) mass in polluted regions, and its modeling remains poorly constrained. A box model is developed that uses recently published literature parameterizations and data sets to better constrain and evaluate the formation pathways and precursors of urban SOA during the CalNex 2010 campaign in Los Angeles. When using the measurements of intermediate-volatility organic compounds (IVOCs) reported in Zhao et al. (2014) and of semi-volatile organic compounds (SVOCs) reported in Worton et al. (2014) the model is biased high at longer photochemical ages, whereas at shorter photochemical ages it is biased low, if the yields for VOC oxidation are not updated. The parameterizations using an updated version of the yields, which takes into account the effect of gas-phase wall losses in environmental chambers, show model-measurement agreement at longer photochemical ages, even though some low bias at short photochemical ages still remains. Furthermore, the fossil and non-fossil carbon split of urban SOA simulated by the model is consistent with measurements at the Pasadena ground site. Multi-generation oxidation mechanisms are often employed in SOA models to increase the SOA yields derived from environmental chamber experiments in order to obtain better model-measurement agreement. However, there are many uncertainties associated with these aging mechanisms. Thus, SOA formation in the model is compared to data from an oxidation flow reactor (OFR) in order to constrain SOA formation at longer photochemical ages than observed in urban air. The model predicts similar SOA mass at short to moderate photochemical ages when the aging mechanisms or the updated version of the yields for VOC oxidation are implemented. The latter case has SOA formation rates that are more consistent with observations from the OFR though. Aging mechanisms may still play an important role in SOA chemistry, but the

      OBJECTIVE To evaluate the impact of consuming ultra-processed foods on the micronutrient content of the Brazilian population's diet. METHODS This cross-sectional study was performed using data on individual food consumption from a module of the 2008-2009 Brazilian Household Budget Survey. A representative sample of the Brazilian population aged 10 years or over was assessed (n = 32,898). Food consumption data were collected through two 24-hour food records. Linear regression models were used to assess the association between the nutrient content of the diet and the quintiles of ultra-processed food consumption - crude and adjusted for family income per capita. RESULTS Mean daily energy intake per capita was 1,866 kcal, with 69.5% coming from natural or minimally processed foods, 9.0% from processed foods and 21.5% from ultra-processed foods. For sixteen out of the seventeen evaluated micronutrients, their content was lower in the fraction of the diet composed of ultra-processed foods compared with the fraction of the diet composed of natural or minimally processed foods. The content of 10 micronutrients in ultra-processed foods did not reach half the content level observed in the natural or minimally processed foods. The higher consumption of ultra-processed foods was inversely and significantly associated with the content of vitamins B12, vitamin D, vitamin E, niacin, pyridoxine, copper, iron, phosphorus, magnesium, selenium and zinc. The reverse situation was only observed for calcium, thiamin and riboflavin. CONCLUSIONS The findings of this study highlight that reducing the consumption of ultra-processed foods is a natural way to promote healthy eating in Brazil and, therefore, is in line with the recommendations made by the Guia Alimentar para a População Brasileira (Dietary Guidelines for the Brazilian Population) to avoid these foods.

      Between 1901-1921, India gained 12.9 million people because mortality remained high. The death rate fell between 1921-1951, but birth rates remained the same. Therefore 110 million people were added--2 times the population increase between 1891-1921. Between 1951-1981, the population increased to 324 million. Socioeconomic development was responsible for most of the downward trend in the birth rate during the 20th century. Even though large families were the norm in early India, religious leaders encouraged small family size. The 1st government family planning clinics in the world opened in Mysore and Bangalore in 1930. Right before Independence, the Bhore Committee made recommendations to reduce population growth such as increasing the age of marriage for girls. Since 1951 there has been a change in measures and policies geared towards population growth with each of the 7 5-Year Plans because policy makers applied what they learned from each previous plan. The 1st 5-Year Plan emphasized the need to understand what factors contribute to population growth. It also integrated family planning services into health services of hospitals and health centers. The government was over zealous in its implementation of the sterilization program (2nd 5-Year Plan, 1956-1961), however, which hurt family planning programs for many years. As of early 1992, sterilization, especially tubectomy, remained the most popular family planning method, however. The 7th 5-Year Plan changed its target of reaching a Net Reproductive Rate of 1 by 2001 to 2006-2011. It set a goal of 100% immunization coverage by 1990 but it did not occur. In 1986, the Ministry of Health and Family Welfare planned to make free contraceptives available in urban and rural areas and to involve voluntary organizations. The government needs to instill measures to increase women's status, women's literacy, and age of marriage as well as to eliminate poverty, ensure old age security, and ensure child survival and

      Intraspecific communication in frogs plays an important role in the recognition of conspecifics in general and of potential rivals or mates in particular and therefore with relevant consequences for pre-zygotic reproductive isolation. We investigate intraspecific communication in Hylodes japi, an endemic Brazilian torrent frog with territorial males and an elaborate courtship behavior. We describe its repertoire of acoustic signals as well as one of the most complex repertoires of visual displays known in anurans, including five new visual displays. Previously unknown in frogs, we also describe a bimodal inter-sexual communication system where the female stimulates the male to emit a courtship call. As another novelty for frogs, we show that in addition to choosing which limb to signal with, males choose which of their two vocal sacs will be used for visual signaling. We explain how and why this is accomplished. Control of inflation also provides additional evidence that vocal sac movement and color must be important for visual communication, even while producing sound. Through the current knowledge on visual signaling in Neotropical torrent frogs (i.e. hylodids), we discuss and highlight the behavioral diversity in the family Hylodidae. Our findings indicate that communication in species of Hylodes is undoubtedly more sophisticated than we expected and that visual communication in anurans is more widespread than previously thought. This is especially true in tropical regions, most likely due to the higher number of species and phylogenetic groups and/or to ecological factors, such as higher microhabitat diversity.

      Full Text Available Currency notes have been implicated as a vehicle for transmitting community-acquired bacterial infections. However, the overall diversity of the bacterial population residing on banknotes is still unknown in Brazil. In this study, we aimed to investigate the overall bacterial population from 150 different Brazilian Rial (R$ notes in circulation using a culture-independent Illumina massively parallel sequencing approach of the 16S rRNA genes. Samples were randomly collected from three different street markets or “feiras” in the metropolitan region of São Paulo. Taxonomical composition revealed the abundance of Proteobacteria phyla, followed by Firmicutes and Streptophyta, with a total of 1193 bacterial families and 3310 bacterial genera. Most of these bacterial genera are of human, animal, and environmental origins. Also, our analysis revealed the presence of some potential pathogenic bacterial genera including Salmonella, Staphylococcus, and Klebsiella. The results demonstrate that there is a tremendous diversity of bacterial contamination on currency notes, including organisms known to be opportunistic pathogens. One of the factors that may contribute to the richness of bacterial diversity in currency notes is personal hygiene. Thus, our results underscore the need to increase public awareness of the importance of personal hygiene of money handlers who also handle food.

    20. Buddhism of Japanese Immigrants within the framework of Brazilian Buddhism

      Full Text Available The article reflects upon Buddhism of Japanese immigrants, which is the historically and numerically most important sub-segment of the so-called “ethnic Buddhism” in Brazil. The latter represents - in distinction from the “Buddhism of converts” - one of the two principles analytical subcategories of Buddhist universe of the country. The text starts with a reconstruction of the trajectory of the religious sub-segment in question by relating it to other observable tendencies in Brazil’s Buddhist field in general. For analytical reasons, the history of Buddhism of Japanese immigrants is subdivided into four phases. In the second part of the article the aforementioned data are interpreted from a sociological point of view. This interpretation refers mainly to the statistics of the National Census from 1950 onwards conducted by the Brazilian Institute of Geography and Statistics (IBGE. The data indicate a gradual decline of Japanese Immigrant Buddhism during the last decades that has cumulated into general crises of the Buddhist segment in question. As for factors possibly responsible for this negative development, the article discusses aspects such as logistical failures on the side of the Buddhist institutions or the difficulties of the families of Japanese descendants in handing down their cultural and religious heritage to their children.

      Full Text Available Determining bee and plant interactions has an important role on understanding general biology of bee species as well as the potential pollinating relationship between them. Bee surveys have been conducted in Brazil since the end of the 1960s. Most of them applied standardized methods and had identified the plant species where the bees were collected. To analyze the most generalist bees on Brazilian surveys, we built a matrix of bee-plant interactions. We estimated the most generalist bees determining the three bee species of each surveyed locality that presented the highest number of interactions. We found 47 localities and 39 species of bees. Most of them belong to Apidae (31 species and Halictidae (6 families and to Meliponini (14 and Xylocopini (6 tribes. However, most of the surveys presented Apis mellifera and/or Trigona spinipes as the most generalist species. Apis mellifera is an exotic bee species and Trigona spinipes, a native species, is also widespread and presents broad diet breath and high number of individuals per colony.

      Full Text Available Abstract: Considering that environmental risk factors substantially contribute to the etiology of orofacial clefts and that knowledge about the characteristics and comorbidities associated with oral clefts is fundamental to promoting better quality of life, this study aimed to describe the risk factors, main characteristics, and comorbidities of a group of patients with cleft lip and/or cleft palate (CL/P from Rio Grande do Norte (RN, Brazil. Data were obtained from 173 patients with CL/P using a form from the Brazilian database on Orofacial Clefts. Most patients were male with cleft lip and palate and had a normal size and weight at birth; presented few neonatal intercurrent events; and had anemia and respiratory and cardiovascular diseases as main associated comorbidities. They also required timely surgical rehabilitation and multidisciplinary care to stimulate their neuropsychomotor development. In addition, a high frequency of familial recurrence and of parental consanguinity was evidenced in the studied population, especially for the cleft lip and cleft palate type. Other relevant findings were the considerable maternal exposure to alcohol, infections, smoking, and hypertension, as well as low supplementation with vitamins and minerals and deliberate consumption of analgesics, antibiotics, and antihypertensives during pregnancy. Characterization of the CL/P patient profile is essential for the planning of health services and integration among the health professionals involved in the diagnosis and treatment of these malformations. Our results reinforce the need for additional research to confirm the association between environmental factors and the development of orofacial clefts.

      Fábio P de Sá

      Full Text Available Intraspecific communication in frogs plays an important role in the recognition of conspecifics in general and of potential rivals or mates in particular and therefore with relevant consequences for pre-zygotic reproductive isolation. We investigate intraspecific communication in Hylodes japi, an endemic Brazilian torrent frog with territorial males and an elaborate courtship behavior. We describe its repertoire of acoustic signals as well as one of the most complex repertoires of visual displays known in anurans, including five new visual displays. Previously unknown in frogs, we also describe a bimodal inter-sexual communication system where the female stimulates the male to emit a courtship call. As another novelty for frogs, we show that in addition to choosing which limb to signal with, males choose which of their two vocal sacs will be used for visual signaling. We explain how and why this is accomplished. Control of inflation also provides additional evidence that vocal sac movement and color must be important for visual communication, even while producing sound.

      Full Text Available ABSTRACT Objective To analyze the prevalence and factors associated with breakfast skipping among adolescents. Methods Cross-sectional study, with adolescents aged 10-17 years, evaluated between 2009 and 2011, belonging to a cohort study in the Central-West region of Brazil. Breakfast skipping was considered as not having breakfast every day. Demographic, socioeconomic, and lifestyle factors were evaluated through a questionnaire. Anthropometric assessment included measurement of weight and height, which were used to classify weight status using body mass index. Poisson regression was used to assess the association of breakfast skipping with demographic and socioeconomic variables, lifestyle factors, and weight status. Results Among 1,716 Brazilian adolescents evaluated, 36.2% reported not consuming breakfast every day, with the highest prevalence among girls (p=0.03. After adjusting for age and economic class, breakfast skipping was associated with not consuming breakfast with parents and morning shift at school, in both genders, and with obesity only in boys. Lifestyle factors such as alcohol consumption, physical activity, diet quality, and smoking were not associated with skipping breakfast. Conclusion The omission of breakfast was observed in more than a third of adolescents, being associated with demographic and lifestyle factors. In the public health perspective, the importance of encouraging the consumption of this meal is highlighted, with actions involving the school environment and the family.

      Regular consumption of a well balanced breakfast is a pre-requisite for normal growth and child development, along with the acquisition of proper eating habits. The family environment is crucial place where children learn such patterns of behaviour that form the basis for their development. To determine how family factors affect the regular eating of breakfast and types of foodstuffs consumed in primary school pupils, including food purchases made from vending machines and school tuck shops. Subjects were 836 pupils (435 girls and 401 boys, aged 6 - 13) from Warsaw and the surrounding areas. Appropriate socio-demographic data and relevant eating habits were obtained from direct interviewing of the subjects by means of a custom designed questionnaire. Statistical analyses were performed by the Kohonen type cluster analysis model and Chi-square test (Chi(2)); (p≤0.05). Three clusters of pupils were identified by their differing socio-demographics and eating habits (eg. rates of breakfast consumption, buying from vending machines or school tuck shops). The first and third clusters were mainly pupils from two-parent families with parents proportionally spending similar times at work, where respective breakfast (87% and 91%) and second breakfast (77% and 72%) consumption rates were also similar together with food shopping rates during school time (respectively 69% and 63%). Pupils with single-parents, multi-generation families or if both parents were profession- ally active, predominated in the second cluster. These ate breakfast (73%) and second breakfast (67%) more rarely, but more frequently shopped for food at school (84%). A small number of pupils had a packed second breakfast from home, rarely ate sandwiches, fruit and/or vegetables and dairy products but ate more sweets, sweet rolls and savoury snacks. However, a large number of subjects bought sandwiches, fresh fruit and/or vegetables and fast-food at school. Family factors were found to affect eating habits

    7. BRAZILIAN PINE NUTS’ PRODUCTION IN CAÇADOR’S REGION, SC: ASPECTS OF THE ATTAINMENT AND ITS IMPORTANCE FOR LOCAL COMMUNITIES

      2010-03-01

      Full Text Available The present study had as objective to characterize aspects of the attainment and commercialization of the Brazilian-pine nut, as a resource capable to contribute for attainment of income and conservation of FOM. For this, studies were carried out aiming at: checking Brazilian-pine production on a natural population (RGFC – Genetic and Forest Reserve of Caçador and on a reforestation with Brazilian-pine (Flona- Caçador’s National Florest; identifying the profile of the Brazilian-pine nut’s collectors in the District of Taquara Verde, Caçador-SC – its knowledge about the resource and the importance of this resource as an income source. For this, 36 female Brazilian-pines were target in Flona and 25 in RGFC. Brazilian-pine nut production was estimated based on the number of female plants, number of cones per plant, number of nut per cone and nut weight. To the other objectives, interviews with the nut’s collectors were made. The production found at RGFC was 44.3kg.ha-1 and at Flona was 24.6kg.ha-1, the difference was attributed to the higher density found at Flona. About the importance of Brazilian-pine nut to the community, it could be found out that this resource is very important both as an income source and food, allowing us to separate the collectors in four kinds of profile. The families which were more dependent on this resource as income, more often they collect and more people in the family are involved in the collection of the Brazilian-pine nut, but not necessary they know more about it. The results of this study indicate a good potential of this resource to increase the household of poor communities, emphasizing the importance of natural areas to the exploration of Brazilian-pine nut and bringing subsidies for the establishment of politics that can effectively join a valuation of the forest resources, the communities’ development together with nature conservation.

      This paper deals with the molecular investigation of Waardenburg syndrome (WS) in a sample of 49 clinically diagnosed probands (most from southeastern Brazil), 24 of them having the type 1 (WS1) variant (10 familial and 14 isolated cases) and 25 being affected by the type 2 (WS2) variant (five familial and 20 isolated cases). Sequential Sanger sequencing of all coding exons of PAX3, MITF, EDN3, EDNRB, SOX10 and SNAI2 genes, followed by CNV detection by MLPA of PAX3, MITF and SOX10 genes in selected cases revealed many novel pathogenic variants. Molecular screening, performed in all patients, revealed 19 causative variants (19/49 = 38.8%), six of them being large whole-exon deletions detected by MLPA, seven (four missense and three nonsense substitutions) resulting from single nucleotide substitutions (SNV), and six representing small indels. A pair of dizygotic affected female twins presented the c.430delC variant in SOX10, but the mutation, imputed to gonadal mosaicism, was not found in their unaffected parents. At least 10 novel causative mutations, described in this paper, were found in this Brazilian sample. Copy-number-variation detected by MLPA identified the causative mutation in 12.2% of our cases, corresponding to 31.6% of all causative mutations. In the majority of cases, the deletions were sporadic, since they were not present in the parents of isolated cases. Our results, as a whole, reinforce the fact that the screening of copy-number-variants by MLPA is a powerful tool to identify the molecular cause in WS patients. Copyright © 2018 Elsevier Masson SAS.

      This study aimed to evaluate the magnitude of and the factors associated with the coexistence of risk behaviors for being overweight among Brazilian adolescents. This is a cross-sectional study with a representative sample of adolescents (mostly aged 13-15years) enrolled from public and private schools of Brazil in 2012. The co-occurring sedentary behavior and inadequate food consumption (regular intake of sugary and fried foods, and irregular consumption of fruits and vegetables-FV) was estimated using a Venn diagram. Sociodemographic, familial, and behavioral factors associated with the number of risk behaviors for being overweight were identified using an ordinal logistic regression analysis. Sedentary behavior was observed in 62.0% of adolescents. Regular intake of sugary or fried food was observed in 55.3% and 23.5% of adolescents, respectively, with 51.9% having an inadequate intake of FV. At least one risk behavior was reported in >90.0% of adolescents; 6.1% reported all 4. Being female, having a higher maternal education level, attending private school, not having breakfast or meals with parents regularly, eat watching television, and not practicing weekly leisure time physical activity were associated with an increased chance of having multiple risk behaviors. This study observed a high prevalence of coexisting of risk behaviors, which was associated with sociodemographic, familial, and behavioral factors. These findings may contribute to a clearer understanding of the associations between different behaviors among adolescents, and may be used to improve public health surveillance and to develop strategies that address multiple behaviors, in order to prevent overweight among adolescents.

      Rising costs and a workforce talent shortage are two of the health care industry's most pressing challenges. In particular, serious illnesses often impose significant costs on individuals and their families, which can place families at an increased risk for multigenerational economic deprivation or even an illness-poverty trap. At the same time, family caregivers often acquire a wide variety of health care skills that neither these caregivers nor the health care industry typically use. As these skills are marketable and could be paired with many existing medical certifications, this article describes a possible "path toward economic resilience" (PER) through a program whereby family caregivers could find meaningful employment using their new skills. The proposed program would identify ideal program candidates, assess and supplement their competencies, and connect them to the health care industry. We provide a set of practical steps and recommended tools for implementation, discuss pilot data on the program's appeal and feasibility, and raise several considerations for program development and future research. Our analysis suggests that this PER program could appeal to family caregivers and the health care industry alike, possibly helping to address two of our health care system's most pressing challenges with one solution.

      1984-01-01

      We reported 63 macrocephalic children with special emphasis on 16 cases with familial macrocephaly. Of the 16 children with familial macrocephaly, 13 were boys. Foureen parents (13 fathers and 1 mother) had head sizes above 98th percentile. Three of 5 brothers and 5 of 8 sisters also had large heads. The head circumference at birth was known for 14 of the children and it was above the 98th percentile in 7 patients. Subsequent evaluations have shown the head size of these children to be following a normal growth curve. Some of the children were hypotonic as infants, but their development was generally normal. CT scans usually clearly distinguished these children from those with hydorocephalus. The familial macrocephalic children had ventricular measurements which were within the normal range, but absolute measurements of the ventricular size may be misleading, because the CT appearance was of mildly dilated ventricles in half of them.

      This special issue includes invited and selected articles of the VIII Brazilian Meeting on Simulational Physics (BMSP), held in Florianópolis, Santa Catarina, Brazil, from 3rd to 8th August, 2015. This is the eighth such meeting, and the second one to have contributed papers published in Journal of Physics: Conference Series (the other was the VII BMSP). The previous meetings in the BMSP series took place in the mountains of Minas Gerais, in the region of the Brazilian Pantanal, and in the shores of Paraíba. Now, for the first time, the Meeting was held in Florianópolis, with its pleasing shores, the capital of Santa Catarina state. The VIII BMSP brought together about 50 researchers from all over the world for a vibrant and productive conference. As in the previous meetings, the talks and posters highlighted recent advances in applications, algorithms, and implementation of computer simulation methods for the study of condensed matter, materials, and out of equilibrium, quantum and biologically motivated systems. We are sure that this meeting series will continue to be an important occasion for people working in simulational physics to exchange ideas and discuss the state of the art of this always expanding field. We are very glad to put together this special issue, and are most appreciative of the efforts of the editors of the Journal of Physics: Conference Series for making this publication possible. We are grateful for the outstanding work of the Florianopolis team, for the financial support of the Brazilian agencies CAPES and CNPq, and of the Federal Universities UFPB and UFSC. At last, but not least, we would like to acknowledge all of the authors for their written submissions. (paper)

    6. The Brazilian external individual monitoring scenario

      In order to improve radiation protection it is necessary to have knowledge of the occupational radiation dose levels in all radiation facilities. This information comes from individual monitoring services, which are responsible for measuring and providing information about workers' radiation exposure. In 1981, the Comissao Nacional de Energia Nuclear (CNEN) of Brazil starts to develop a comprehensive system for regulation and storage of occupational radiation dose. This paper starts with an overview of the evolution of the Brazilian authorization and data storage system for external individual monitoring. It starts with a rule for authorization of all Brazilian photon individual monitoring services and the obligation for them to send the measured dose to CNEN. Up to now there is no regulation for neutron individual monitoring. The aim of this paper is to present the current scenario of the Brazilian external monitoring system, reinforcing its importance and remaining problems. The number of monitored workers greatly increases every year, having surpassed 150,000 people monitored. The stored data show that the mean annual occupational external dose is decreasing from 2.4 mSv in 1987 to about 0.6 mSv, in 2012, but there is still some not realistic very high dose measured (higher than 100 mSv), without investigation. About 80% of the annual dose values are lower than the monthly register level. As expected, the higher real photon doses are found in Nuclear Medicine, Industrial Radiology and Interventional Radiology. All recorded annual neutron dose values are lower than 20 mSv. (author)

      The topic of tobacco smoking, in its several aspects, has been receiving increasing attention among researchers over the past few years, which has been reflected in more data and more solid scientific literature on the subject in national journals. This article aims to review the studies that focused on smoking published between January 2010 and June 2012, in Arquivos Brasileiros de Cardiologia (Brazilian Archives of Cardiology), Brazilian Journal of Medical and Biological Research, Clinics (Sao Paulo), Jornal Brasileiro de Pneumologia (Brazilian Journal of Pulmonology), Revista da Associação Médica Brasileira (Journal of the Brazilian Medical Association) and Revista Brasileira de Cirurgia Cardiovascular (Brazilian Journal of Cardiovascular Surgery). During the aforementioned period 58 articles were published, 52 of which were original ones, addressing several aspects of smoking, such as effects on health, epidemiology, cessation and experimental studies.

      Identifying knowledge about factors associated with health risk behaviors among Brazilian adolescents. An integrative review of the literature conducted in the Cochrane, IBECS, LILACS, MEDLINE and SciELO databases in relation to risk behaviors recommended by the Centers for Disease Control and Prevention. Thirty-seven (37) studies were analyzed, with a predominance of risky sexual behavior, tobacco use and violent behavior. Advancing age favored unprotected sex, alcohol and tobacco use. Family and friends influence was related to smoking and alcoholism. Males were more involved in situations of violence and the female gender was associated with physical inactivity. Belonging to a lower economic class was related to unprotected sex, physical inactivity, unhealthy dietary behaviors and violence. Studying in private school was related to unhealthy dietary behavior. Risk behaviors were related to social, economic and family factors and they tend to agglomerate.

      Full Text Available Hepatitis C virus (HCV (genus Hepacivirus; family Flaviviridae is a major human pathogen causing persistent infection and hepatic injury. Recently, emerging HCV-like viruses were described infecting wild animals, such as bats and rodents, and domestic animals, including dogs, horses, and cattle. Using degenerate primers for detecting bovine pestiviruses in a 1996 survey three bovine serum samples showed a low identity with the genus Pestivirus of the Flaviviridae family. A virus could not be isolated in cell culture. The description of bovine hepaciviruses (BovHepV in 2015 allowed us to retrospectively identify the sequences as BovHepV, with a 88.9% nucleotide identity. In a reconstructed phylogenetic tree, the Brazilian BovHepV samples grouped within the bovine HCV-like cluster in a separated terminal node that was more closely related to the putative bovine Hepacivirus common ancestor than to bovine hepaciviruses detected in Europe and Africa.

      Sand samples collected on the beaches of the 'radioactive' Brazilian town of Guarapari were first separated by flotation in bromoform and successively divided into various magnetic fractions with a Franz isodynamic separator. concentrations of background radionuclides in samples of monazite, ilmenite, and zircon were determined by a γ-ray spectrometer. Chemical composition of monazite, ilmenite and magnetite were assessed by means of an electron microprobe. Monazite resulted to be relatively rich in ThO 2 whose abundance ranged from 5.3 to 7.7 (wt%). (author)

      Full Text Available The main aim of this paper was to present some pioneer women neurologist, their struggle to pursue their career and the barriers mainly encountered at the beginning of their professional lives. It was also presented the progressive increasing of the feminine participation in medicine and in the neurology with study based on data of the School of Medicine of the Federal University of Rio de Janeiro and Brazilian Academy of Neurology. Their composition were analyzed according to gender, class and academic rank. In spite of this feminization, there is lack of a women's parallel advancement into leadership positions despite no visible barriers ("glass ceiling".

    12. The Brazilian deindustrialization: financialization is not guilty

      Full Text Available The financialization of the Brazilian economy is often criticized as being responsible of the slowdown of capital accumulation in this country. Indeed, very high interest rates are maintained in order to finance the public debt, and this fosters capitalists to get more Treasury bonds rather than to invest in the productive area. Nevertheless, the evolution of the profit rate in this area also explains the particular relation existing between capitalists, finance and productive investment, as Marx showed it more than a century ago.

      Full Text Available This paper relies on some data to identify the 19th century as the major period in which Brazil economy lagged behind some chosen benchmarking countries, as the USA, Canada, New Zealand, Australia and some European periphery countries. To identify the reasons for this an exercise using immigration data was used to make a decomposition of the sources of growth of the proportion of the USA per capita GDP to the Brazilian one. The results indicate that the imported human capital was responsible for 59% to 88% of this total growth between 1820 and 1900.

      Drawing on the interplay between gender, aging, and sexuality, the aim of this article is twofold: (1) to show how Brazilian gerontologists treat gender differences and sexual activity in old age; (2) to analyze the  ways  discourses regarding the aging body and sexuality are perceived and evaluated by older women and men . I argue that  attempts of gerontologists’ to eroticize old age have to contend with the widespread notion that the desire for sex is inevitably lost with age. Thus, in the...

      Full Text Available In this study, we screened sixty medicinal plant species from the Brazilian savanna ("cerrado" that could contain useful compounds for the control of tropical diseases. The plant selection was based on existing ethnobotanic information and interviews with local healers. Plant extracts were screened for: (a molluscicidal activity against Biomphalaria glabrata, (b toxicity to brine shrimp (Artemia salina L., (c antifungal activity in the bioautographic assay with Cladosporium sphaerospermum and (d antibacterial activity in the agar diffusion assay against Staphylococcus aureus, Escherichia coli, Bacillus cereus and Pseudomonas aeruginosa. Forty-two species afforded extracts that showed some degree of activity in one or more of these bioassays.

      With the financial market globalization, foreign investments became vital for the economies, mainly in emerging countries. In the last decades, Brazilian exchange rates appeared as a good indicator to measure either investors' confidence or risk aversion. Here, some events of global or national financial crisis are analyzed, trying to understand how they influenced the "dollar-real" rate evolution. The theoretical tool to be used is the López-Mancini-Calbet (LMC) complexity measure that, applied to real exchange rate data, has shown good fitness between critical events and measured patterns.

    17. BRAZILIAN EDUCATION AND SURVIVAL STRATEGIES OF CAPITALISM

      Full Text Available In discussing the theme Imperialism, Crisis and education, the essay points out aspects of our historical totality in relation to recent crises through which it passed capitalism, and its relationship to changes in Brazilian educational policies. Education remains at the heart of development projects, as a producer of knowledge, as well as guiding the processes of social conformation. They also discussed the aftermath of the crisis: the rise of social inequality and the increase of labor exploitation. Make clear our project of society and education, as resistance movements to the survival of capitalism is a necessity in building movements of counter-hegemony.
