1. Stressful life events and hopelessness in adults: the mediating role of mentalization and emotional dysregulation
Objective: Hopelessness is considered a risk factor for several mental and behavioral disorders. Research has shown that a stressful life event can be a significant predictor of hopelessness. The aim of the current research study was to explore the relationship between stressful life events and hopelessness, as well as to analyses the mediation effect of bo

2. Estimating the rock mass deformation modulus: A comparative study of empirical methods based on 48 rock mass scenarios
Abstract The rock mass deformation modulus, Erm, is an input parameter for most numerical modeling to verify the deformation behavior of rocks due to rock engineering activities within/on it. Among the most common methodologies used for estimating this parameter, empirical correlations based on rock mass classification schemes (e.g., RQD, RMR, GSI, and Q) st

3. Contribution to hierarchical modeling in tunnel design practice
Resumo Esse trabalho apresenta uma análise comparativa entre duas hierarquias de modelos comumente aplicadas no projeto estrutural de túneis: modelos de maciço contínuo e de anel sobre apoios. Primeiramente, as principais características de cada modelo e as interfaces entre ambos são discutidas. Baseado em tais avaliações um procedimento simples é p

4. Consumo de Jornal Impresso e Online: Impresso é Status, Online é Facilidade
Resumo O jornal online tem demonstrado crescente utilização, podendo representar um potencial risco para o mercado de jornal impresso. Para investigar este mercado, o estudo objetiva avaliar como variáveis motivacionais (i.e., valores humanos e axiomas sociais) e os julgamentos afetivo e racional influenciam, comparativamente, o uso de jornal impresso e o

5. Component mechanisms of executive function in schizophrenia and their contribution to functional outcomes
Objective: In schizophrenia, scores reflecting deficits in different cognitive processes are strongly correlated, making it difficult to establish a solid relationship between different cognitive mechanisms and other features of this disorder. The objective of this study was to explore whether three frequently postulated executive functions (updating, shift

6. Behavior and design of built-up compressed steel members composed of concentric hot rolled circular hollow sections
Abstract This research presents a study of the behavior of built-up compressed steel members composed of concentric hot rolled circular hollow sections. The use of these members is an innovative solution of practical interest for situations in which a single member does not reach the required compressive strength. Some technically and economically viable de

7. Psychological model of ART adherence behaviors in persons living with HIV/AIDS in Mexico: a structural equation analysis
ABSTRACT OBJECTIVE The objective of this study has been to test the ability of variables of a psychological model to predict antiretroviral therapy medication adherence behavior. METHODS We have conducted a cross-sectional study among 172 persons living with HIV/AIDS (PLWHA), who completed four self-administered assessments: 1) the Psychological Variable

8. Structural insights into leishmanolysins encoded on chromosome 10 of Leishmania (Viannia) braziliensis
BACKGROUND Leishmanolysins have been described as important parasite virulence factors because of their roles in the infection of promastigotes and resistance to host’s defenses. Leishmania (Viannia) braziliensis contains several leishmanolysin genes in its genome, especially in chromosome 10. However, the functional impact of such diversity is not under

9. Brazoides A-D, New Alkaloids from Justicia gendarussa Burm. F. Species
Four new alkaloids, Brazoides A-D, together with three known compounds squalene, β-sitosterol and lupeol, were isolated from leaves of Justicia gendarussa. These structures were established by spectrometric techniques, mainly high-resolution electrospray ionization mass spectrometry (HRESIMS) and 1D and 2D nuclear magnetic resonance (NMR), including compara

10. QSAR Study of the Inhibitors of the Acetyl-CoA Carboxylase 1 and 2 using Bayesian Regularized Genetic Neural Networks: A Comparative Study
Linear and non-linear quantitative structure-activity relationship (QSAR) models were presented for modeling and predicting anti-diabetic activities of a set of inhibitors of acetyl-CoA carboxylase 1 and 2 (ACC1 and ACC2). Different algorithms were utilized to choose the best variables among large numbers of descriptors and then these selected descriptors we

11. A comparative study on propagation of elastic waves in random particulate composites
This paper aims to conduct a comparative study on four different models of effective field and effective medium for modeling propagation of plane elastic waves through the composites containing spherical particles with random distribution. Effective elastic properties along with the normalized phase velocity and attenuation of the average wave was numericall

12. Factors affecting mobile users' switching intentions: a comparative study between the brazilian and german markets
In the competitive wireless market, there are many drivers behind customer defection. Switching barriers, service performance, perceived value in carriers' offers, satisfaction and other constructs can play a pivotal role in customer switching processes among carriers. This study attempts to compare the influence of these factors, taking into account cultura
