A linear, second-order, energy stable, fully adaptive finite-element method for phase-field modeling of wetting phenomena

We propose a new numerical method to solve the Cahn-Hilliard equation coupled with non-linear wetting boundary conditions. We show that the method is mass-conservative and that the discrete solution satisfies a discrete energy law similar to the one satisfied by the exact solution. We perform several tests inspired by realistic situations to verify the accuracy and performance of the method: wetting of a chemically heterogeneous substrate in three dimensions, wetting-driven nucleation in a complex two dimensional domain and three-dimensional diffusion through a porous medium

Internal and external threat in relationship with right-wing attitudes

Objective Previous studies on the relationship between threat and right-wing attitudes have tended to focus on either internal threat, emanating from one's private life, or external threat, originating from society. However, these studies failed to examine whether these types of threats constitute two distinctive dimensions and which of these threats is most closely related to right-wing attitudes. Method In order to explore the dimensions underlying threat, a factor analysis on a variety of threat scales was conducted (Study 1; N?=?300). Furthermore, in a meta-analysis (Study 2; total N?=?22,086) and a questionnaire study in a large representative sample (Study 3, N?=?800) the strength of the relationships of internal and external threat with right-wing attitudes were investigated. Results The present studies revealed that internal and external threat can be considered as two distinct dimensions underlying threat. Moreover, whereas external threat yielded strong relationships with right-wing attitudes, internal threat only explained a minor part of the variance in these attitudes. Conclusions External rather than internal threat underlies the relationship between threat and right-wing attitudes

Karyotype Evolution in Birds: From Conventional Staining to Chromosome Painting.

In the last few decades, there have been great efforts to reconstruct the phylogeny of Neoaves based mainly on DNA sequencing. Despite the importance of karyotype data in phylogenetic studies, especially with the advent of fluorescence in situ hybridization (FISH) techniques using different types of probes, the use of chromosomal data to clarify phylogenetic proposals is still minimal. Additionally, comparative chromosome painting in birds is restricted to a few orders, while in mammals, for example, virtually all orders have already been analyzed using this method. Most reports are based on comparisons using Gallus gallus probes, and only a small number of species have been analyzed with more informative sets of probes, such as those from Leucopternis albicollis and Gyps fulvus, which show ancestral macrochromosomes rearranged in alternative patterns. Despite this, it is appropriate to review the available cytogenetic information and possible phylogenetic conclusions. In this report, the authors gather both classical and molecular cytogenetic data and describe some interesting and unique characteristics of karyotype evolution in birds

Childhood maltreatment, personality vulnerability profiles, and borderline personality disorder symptoms in adolescents

Adverse childhood experiences are significant risk factors in the development of adolescent borderline personality disorder symptoms (BPDs). Theorists have posited that two personality vulnerabilities factors, self-criticism and dependency, may inform our understanding of this relationship. However, no research has examined the associations between early negative experiences, personality vulnerabilities, and adolescent BPDs. The current study aimed to identify profiles of dependency and self-criticism to examine the associations of these profiles with cumulative forms of childhood maltreatment (CM) and BPDs as well as to explore the mediating and moderating role of vulnerable personality profiles in the relationship between cumulative CM and BPDs. Two hundred and forty-one nonclinical and clinical adolescents participated in the study (Mage = 16.37, SD = 1.84). The findings indicated three different profiles: average dependent profile, dependent and self-critical profile, and self-critical profile. Individuals in the average dependent profile presented lower levels of CM and BPDs. Mediation analyses showed that relative to the average dependent profile, a higher cumulative CM history predicted a higher probability of belonging in the dependent and self-critical profile or the self-critical profile and, in turn, this was associated with higher levels of BPDs. No moderating effects of profiles of dependency and self-criticism were found

Heroes and villains of world history across cultures

Multidimensional scaling and factor analysis techniques found only limited forms of universality in evaluations across Western, Catholic/Orthodox, Muslim, and Asian country clusters. The highest consensus across cultures involved scientific innovators, with Einstein having the most positive evaluation overall. Peaceful humanitarians like Mother Theresa and Gandhi followed. There was much less cross-cultural consistency in the evaluation of negative figures, led by Hitler, Osama bin Laden, and Saddam Hussein. After more traditional empirical methods (e.g., factor analysis) failed to identify meaningful cross-cultural patterns, Latent Profile Analysis (LPA) was used to identify four global representational profiles: Secular and Religious Idealists were overwhelmingly prevalent in Christian countries, and Political Realists were common in Muslim and Asian countries. We discuss possible consequences and interpretations of these different representational profiles.This research was supported by grant RG016-P-10 from the Chiang Ching-Kuo Foundation for International Scholarly Exchange (http://www.cckf.org.tw/).

The Italian version of the Depressive Experiences Questionnaire: psychometric properties and validation in students, community, and clinical groups

The current study evaluated the psychometric properties of the Italian validation of the Depressive Experiences Questionnaire (DEQ), conceived as a measure of self-criticism and dependency, i.e. two personality factors acting, according to Blatt (2004), as risk factors for depression in particular and psychopathology in general. A series of standardized measures [Beck Depression Inventory-II (BDI-II), DEQ, Symptom Checklist-90-R (SCL-90-R), Millon Clinical Multiaxial Inventory, 3rd edition (MCMI-III)] was administered to three samples (i.e., students, community and clinical). Factorial validity was evaluated along with convergent and predictive validity. In order to evaluate the reliability and internal consistency, a specific subgroup of participants was retested on the DEQ and BDI-II. Results showed correlations between DEQ dimensions and some personality traits of the MCMI-III. The traditional three-factor model of the DEQ structure as identified by principal component analysis appears to be as stable factors as typically found in American samples, although some items showed elevated cross-loading or low loadings on any factor. Clinical and diagnostic implications of the findings will be discussed
