Abstract: Brazil is considered a megadiverse country, but the soil fauna is still very poorly known. The aim of this study was to report, for the fi rst time, the abundance and genus composition of terrestrial enchytraeids (Enchytraeidae, Oligochaeta) in Savanna Tall Woodland (Cerradão) and a pasture in Cerrado Biome and in Upper Montane Atlantic Forest and a grassland in Atlantic Forest Biome. The enchytraeid density in Pasture and Cerradao was 2,036 and 18,844 (204 and 2,094, on average) individuals per square meter, respectively. At the Atlantic forest and Grassland, density was 9,666 and 12,242 individuals per square meter (1,075 and 1,471 on average). About genus composition for the studied areas, Enchytraeus and Hemienchytraeus were found in the four ecosystems evaluated, while Tupidrilus and Fridericia were found only in Cerradão and Atlantic Forest, respectively. Achaeta was absent in Upper Montane Atlantic Forest, but dominant in pasture, while Guaranidrilus was absent in Pasture, but predominant in the other ecosystem
De onde vem o endividamento feminino?: construção e validação de um modelo PLS-PM Where does the women debt come from?: construction and validation of a PLS-PM model
O consumo exacerbado pode levar muitos indivíduos a contraírem dívidas comprometendo uma parcela significativa de suas rendas e, em muitos casos, acabando por ser tornarem inadimplentes. A inadimplência trás consigo efeitos muitas vezes arrasadores tanto do ponto de vista macroeconômico, aumentando o risco das operações e produtos financeiros, como do ponto de vista do indivíduo, ao afetar suas relações sociais, seu estado psicológico e sua vida familiar. Por outro lado, a maior participação da mulher no mercado de trabalho trouxe uma maior independência financeira e consequentente maior poder na decisão de consumo e ao mesmo tempo, maiores responsabilidades sobre o gerenciamento financeiro e nas decisões de endividamento. Neste sentido, este estudo centrou-se na identificação e análise dos fatores que afetam na propensão ao endividamento, nas mulheres da Mesorregião Centro Ocidental Rio-grandense. Assim, este trabalho propõe um modelo estrutural para explorar as relações entre os fatores determinantes da propensão ao endividamento junto às mulheres da referida Mesorregião, considerando variáveis que compõem os construtos de STATUS SOCIAL, PREOCUPAÇÃO, ESTABILIDADE, PRAZER, PODER, ORÇAMENTO, ILUSÃO e MATERIALISMO. Para isso, foram aplicados 2.500 questionários espalhados estatisticamente entre os 31 municípios que compõem esta Mesorregião. Os dados foram analisados através da metodologia Partial Least Squares - Path Modeling (PLS-PM). Sumariamente, os resultados sugerem que o construto ENDIVIDAMENTO está associado aos construtos STATUS, PREOCUPAÇÃO e MATERIALISMO, corroborando com as teorias das Finanças Comportamentais, ao sugerir que as decisões que envolvem endividamento vão além da simples relação consumo e renda, ou seja, existem outras variáveis comportamentais que são importantes na hora do indivíduo contrair dívidas, tais como, o significado que o indivíduo atribui ao dinheiro e o nível de materialismo.<br>The exacerbate consumption may lead many individuals to contract debts which commite a significant portion of their income and, in many cases, eventually taking into default. The default often brings with it devastating effects in both macroeconomic point of view, increasing the risk of operations and financial products, such as from the individual standpoint, affecting his social, psychological state and family life. Moreover, the bigger women participation in labor market brought greater financial independence and empowerment in decision and consequently larger power of consumption decision and at the same time, more responsibility on financial management and borrowing decisions. Thus, this study focused on the identification and analysis of factors which affect the indebtedness propensity, among women in the Rio Grande do Sul western-central mesoregion. This study proposes a structural model to determine the relationships among the women indebtedness propensity determinants of that mesoregion, considering variables which compose the constructs of SOCIAL STATUS, CONCERN, STABILITY, PLEASURE, POWER, BUDGET, ILLUSION and MATERIALISM. For this, were applied 2,500 questionnaires statistically scattered among the 31 cities which compose the mesoregion. Data were analyzed by Partial Least Squares -Path Modeling (PLS-PM) methodology. In summary, the results suggest that the construct INDEBTEDNESS is associated with SOCIAL STATUS, CONCERN and MATERIALISM, corroborating with the Behavioral Finance theories, suggesting that decisions involving borrowing go beyond the simple consumption and income relationship, i.e., there are other behavioral variables which are important in the time that individual contract debts, such as the meaning that the individual attaches to money and the materialism level
