O terceiro setor e sua rela??o com o estado: compreendendo as atividades de uma cooperativa de apicultores
O estudo versa sobre a articula??o que potencializa a din?mica do di?logo em defesa dos tr?s sustent?culos elementares que comp?em a sociedade contempor?nea: o Estado, o mercado (cooperativas) e o Terceiro Setor. Desse modo, o estudo objetiva compreender as atividades da Cooperativa dos Apicultores de Itaporanga e Regi?o (CAPIR) e sua rela??o com o Estado. O l?cus de investiga??o ? a CAPIR, inserida no Programa de Redu??o da Pobreza Rural (PRPR), com a??es direcionadas para sua atua??o antes da parceria firmada com o Projeto Cooperar, vinculado ? Secretaria de Planejamento e Gest?o do Governo do Estado da Para?ba, e seus resultados ap?s a parceria. A pesquisa ? de car?ter qualitativo e descritivo, em que se utilizou a estrat?gia de estudo de caso ?nico, o tratamento dos dados se deu por meio do NVIVO (vers?o 8.0) e foi utilizado juntamente com uma abordagem indutiva sob an?lise tem?tica de conte?do (BARDIN, 2011; MINAYO, 2010), desenvolvida com dados obtidos por entrevistas semiestruturadas realizadas junto aos cooperados com uso da t?cnica n?o probabil?stica de snowball e com o agente regional do Cooperar que acompanhou o projeto em toda sua extens?o. Os resultados apontaram que a contribui??o do cooperar foi essencial no processo de crescimento da CAPIR e desenvolvimento socioecon?mico de seus cooperados, revelando o esfor?o multifuncional que perpassa a a??o desse tipo de coopera??o
An analysis of human resources management practices of organizations from the perspective of gender diversity.
A presente pesquisa teve como objetivo analisar as pr?ticas de gest?o de pessoas adotadas pelas organiza??es, sob a ?tica da desigualdade de g?nero. Para isso, realizou-se um estudo de casos m?ltiplos, pesquisando-se quatro organiza??es. Analisando os dados coletados, evidenciou-se a dificuldade de se lidar com a desigualdade de g?nero no ?mbito organizacional, visto que as empresas estudadas negam a exist?ncia de tal distor??o e, por conseguinte, ignoram a necessidade de criarem pol?ticas para resolverem o problema. Mesmo com v?rios estudos apontando a diversidade da for?a de trabalho como fator positivo para a empresa, os dados obtidos parecem sinalizar que as organiza??es preferem manterem-se indiferentes quanto ao problema do tratamento desigual destinado a homens e mulheres. A contribui??o deste trabalho reside na identifica??o de alguns gargalos nas pr?ticas de gest?o de pessoas adotadas pelas organiza??es, no que diz respeito ? quest?o da diversidade de g?nero. Espera-se, com isso, que esta pesquisa auxilie gestores na redefini??o de pol?ticas organizacionais relacionadas ? flexibiliza??o do trabalho, remunera??o e carreira, tornando o ambiente corporativo mais equ?nime para homens e mulheres.This study aimed to analyze people management practices adopted by organizations from the perspective of gender inequality. For this, we carried out a study of multiple cases, researching four organizations. The collected data show the difficulty of dealing with gender inequality in the organizational context, since the studied companies deny the existence of such distortion and therefore ignore the need to create policies to solve the problem. Even with several studies pointing to the diversity of the workforce as a positive factor for the company, the data obtained seems to indicate that organizations prefer to remain indifferent to the problem of unequal treatment to men and women. The contribution of this work lies in the identification of some bottlenecks in human resource management practices adopted by organizations, with regard to the issue of gender diversity. Thus, it is expected that this research supports the managers in redefining organizational policies related to flexible working, remuneration and career, making more equitable business environment for men and women
TIPO DE MINIESTACA E DE SUBSTRATO NA PROPAGA\uc7\uc3O VEGETATIVA DE ANGICO-VERMELHO ( Anadenanthera macrocarpa (Benth.) Brenan)
O presente trabalho teve o objetivo de avaliar o efeito da
redu\ue7\ue3o da \ue1rea foliar de miniestacas apicais e
intermedi\ue1rias e de diferentes substratos (vermiculita e composto
org\ue2nico) no enraizamento de seis prog\ueanies de
meios-irm\ue3os de Anadenanthera macrocarpa a partir de minicepas
de origem seminal. As avalia\ue7\uf5es foram realizadas na
sa\uedda da casa de vegeta\ue7\ue3o (30 dias) e da casa de sombra
(40 dias) para sobreviv\ueancia e exposi\ue7\ue3o de ra\uedzes
na extremidade inferior do tubete. Na fase de crescimento a pleno sol,
aos 70 dias ap\uf3s o estaqueamento, foi avaliado o percentual de
sobreviv\ueancia, enraizamento, altura, di\ue2metro de colo,
n\ufamero de ra\uedzes e massa seca da parte a\ue9rea e da raiz
das miniestacas enraizadas. Observou-se para tipo de substrato e tipo
de miniestacas diferen\ue7a entre as prog\ueanies quanto \ue0s
caracter\uedsticas analisadas. O substrato \ue0 base de vermiculita
proporcionou maiores m\ue9dias quanto \ue0 sobreviv\ueancia,
enraizamento, altura, di\ue2metro do colo e peso de massa seca de
raiz. De modo geral, para sobreviv\ueancia, enraizamento, n\ufamero
de ra\uedzes e massa seca da parte a\ue9rea e da raiz constatou-se
que, independentemente da prog\ueanie, a miniestaca apical com 10 cm
de comprimento e com a folha inteira apresentou maiores m\ue9dias.
Portanto, utilizando a vermiculita como substrato as miniestacas
apicais com 10 cm de comprimento e folha inteira mostraram-se mais
adequadas \ue0 propaga\ue7\ue3o vegetativa de material seminal de
Anadenanthera macrocarpa por miniestaquia.This paper aimed to evaluate the effect of leaf area reduction of
apical and intermediate mini-cuttings and different substrates
(vermiculite and organic substrate) on the rooting of six half-sib
Anadenanthera macrocarpa progenies from mini-stumps of seminal
origin. The evaluations were carried out in the greenhouse (30 days)
and the shade house (40 days) for survival rate and roots percentage
observed at the bottom of the container. Survival rate and rooting
percentage, height, stem diameter, number of roots, and dry mass of
shoot and roots of mini-cuttings were evaluated, in the full sunlight
area, 70 days after staking. The results showed that are not
differences between progenies for type of mini-cuttings and substrate
to characteristics evaluated. The vermiculite substrate provided the
best results for the survival rate, rooting percentage, height, stem
diameter and weight of dry roots. In general terms, apical
mini-cuttings up to 10 cm in length and entire leaf had higher averages
survival rate, rooting percentage, root number and dry weight of shoot
and root. Therefore, using vermiculite as substrate, apical
mini-cuttings up to 10 cm in length and entire leaf were more
appropriate for vegetative propagation from seminal material of
Anadenanthera macrocarpa by mini-cutting technique
Phytosociology of the herbaceous-subshrub layer of a rupestrian complex in Serra do Espinha?o, Brazil.
Rupestrian complexes of the Serra do Espinha?o are recognized for their high degree of biodiversity and endemism. However, environmental impacts, particularly from mining, have degraded these environments. The purpose of this study was to describe the herbaceous-subshrub communities that occur in quartzitic (QRC) and ferruginous (FRC) rupestrian complexes in different seasons of the year, with regard to floristic similarity and phytosociological structure. Additionally, the study aimed to identify native species with potential use for the restoration of similar degraded areas. Vegetation was sampled from plots located in the municipality of Concei??o do Mato Dentro, state of Minas Gerais. Five contiguous strata of 10 ? 50 m were demarcated in each environment, in which 12 plots of 2 ? 1 m (2 m?) were randomly distributed, for a total of 60 plots (sample units) in each physiognomy. The studied communities exhibited few similarities and lower floristic diversity than other rupestrian complexes. Detrended correspondence analysis distinguished the communities of FRC from those of QRC. The species with the highest value of importance in FRC were Bulbostylis fimbriata and Centrosema brasilianum, while in QRC Echinolaena inflexa had the highest values, thus, making them eligible for restoration programs in similar environments
CTLA-4 gene polymorphisms are associated with obesity in Turner syndrome
Turner syndrome (TS) is characterized by a set of clinical conditions, including autoimmune/inflammatory diseases and infectious conditions, that can compromise a patient's quality of life. Here we assessed polymorphisms in CTLA-4 +49A/G (rs231775), PTPN22 +1858G/A (rs2476601), and MBL2 -550 (H/L) (rs11003125), -221(X/Y) (rs7096206) and exon 1 (A/O) in women from northeastern Brazil to determine whether polymorphisms within these key immune response genes confer differential susceptibility to clinical conditions in TS. A case-control genetic association study was performed, including 86 female TS patients and 179 healthy women. An association was observed for the A/G genotype of CTLA-4 +49A/G in TS patients (p=0.043, odds ratio [OR]=0.54). In addition, an association between the CTLA-4 G/G genotype and obesity was detected in TS patients (p=0.02, OR=6.04). Regarding, the -550(H/L) polymorphism in the MBL2 promoter, the frequency of the H/L genotype was significantly higher in the TS group than healthy controls (p=0.01, OR=1.96). The H/H genotype indicated a protective effect in TS patients (p=0.01, OR=0.23). No differences were observed in the distribution of -221(X/Y), MBL2 exon 1 variants, and PTPN22 +1858G/A in any assessed groups. CTLA-4 variants are potentially involved in obesity in this cohort of TS patients from northeastern Brazil
The life cycle as a curricular proposal for teaching science and biology in the training of young people and adults in basic education.
Recentemente, a Educa??o de Jovens e Adultos (EJA) vem se configurando como um campo
pedag?gico comprometido com o desenvolvimento de reflex?es cr?ticas sobre suas necessidades e
objetivos. Entretanto, poucos esfor?os v?m sendo feitos no sentido de explicitar ou discutir seus
contornos e especificidades neste campo do conhecimento. Assim, o objetivo basilar deste trabalho
? registrar a trajet?ria percorrida na elabora??o de uma proposta curricular significativa para o
ensino de ci?ncias e biologia, priorizando os tempos e os ritmos de aprendizagem do estudante na
modalidade EJA. Como metodologia, utilizamos a an?lise documental dos documentos advindos do
Minist?rio da Educa??o e da Secretaria Estadual de Educa??o do Estado do Rio de Janeiro, assim
como a colabora??o de professores da rede estadual de ensino do Rio de Janeiro, por meio de
audi?ncias p?blicas. Este trabalho resultou em uma proposta curricular de forma??o generalista,
inspirado no ciclo da vida, organizado por temas, compet?ncias e habilidades dentro de um per?odo
de 01 (um) ano e meio de forma??o.Recentemente, a Educa??o de Jovens e Adultos (EJA) vem se configurando como um campo pedag?gico comprometido com o desenvolvimento de reflex?es cr?ticas sobre suas necessidades e objetivos.

Kinetics of magnetic ageing of 2%Si non-oriented grain electrical steel.
The effect of carbon content on the magnetic ageing index and Vickers hardness evolution on annealed samples of 2%Si non-oriented grain electrical steel was studied. Samples with 40 and 60ppm carbon content were subjected at ageing temperatures of 200 and 225?C, respectively. During the ageing treatment, the cycle was interrupted on several time intervals in order to obtain the core loss and to determine Vickers hardness. The precipitates were characterized using scanning electron microscope (SEM). Using the software MatCalc, computer simulations of ?-carbide precipitation were performed and compared with experimental data from literature. The results for both carbon contents showed that the maximum hardness value was achieved in shorter time than that to achieve the maximum magnetic ageing, indicating that the critical size of precipitates more harmful to the magnetic properties is larger than the ones that maximize the hardness
Record of Early Tonian mafic magmatism in the central Espinha?o (Brazil) : new insights for break-up of the Neoproterozoic landmass ancestor of S?o Francisco-Congo paleocontinent.
Petrological characterization, U?Pb geochronology, Lu?Hf analyses and major and trace element data from mafic intrusions in the Central Espinha?o (central portion of the Brazilian shield) are used here to investigate the geological significance of the Early Neoproterozoic magmatism in the context of the S~ao Francisco-Congo paleocontinent. These mafic bodies are represented by medium to coarse-grained metagabbros with plagioclase, amphibole and clinopyroxene. Zircon U?Pb isotopic data from two samples yielded weighted mean 206Pb/238U ages of 895 3.4 Ma (MSWD ? 1.7) and 896 2.4 Ma (MSWD ? 0.64), regarded as the best estimates for the crystallization age of these mafic rocks. Major and trace element data (including REEs) show that the gabbros originated from a subalkaline tholeiitic magma, typical of intraplate magmatism. Such rocks are slightly enriched in LREEs and LILEs and depleted in HFSEs. Our new isotope and geochemical data, along with regional knowledge, indicate that these metagabbros mark the beginning of an important Tonian-age extensional tectonic event of the landmass of which the S~ao Francisco-Congo paleocontinent was part (Rodinia supercontinent or Central African block?). We furthermore suggest that these rocks belong to a prominent suite of Tonian-age mafic rocks that mark a diachronic breakup attempt of this landmass which may have occurred from south to north along the Espinha?o mountain range
