Interspecific attraction between ground-nesting songbirds and ants: the role of nest-site selection
2021
Abstract Background Interspecific interactions within ecological networks can influence animal fitness and behaviour, including nest-site selection of birds and ants. Previous studies revealed that nesting birds and ants may benefit from cohabitation, with interspecific attraction through their nest-site choice, but mutual interactions have not yet been tested. We explored a previously undescribed ecological link between ground-nesting birds and ants raising their own broods (larvae and pupae) within the birds’ nests in a temperate primeval forest of lowland Europe. We tested whether the occurrence of ant broods within bird nests resulted from a mutual or one-sided interspecific attraction …
The Role of Low Complexity Regions in Protein Interaction Modes: An Illustration in Huntingtin
2021
Low complexity regions (LCRs) are very frequent in protein sequences, generally having a lower propensity to form structured domains and tending to be much less evolutionarily conserved than globular domains. Their higher abundance in eukaryotes and in species with more cellular types agrees with a growing number of reports on their function in protein interactions regulated by post-translational modifications. LCRs facilitate the increase of regulatory and network complexity required with the emergence of organisms with more complex tissue distribution and development. Although the low conservation and structural flexibility of LCRs complicate their study, evolutionary studies of proteins …
Disentangling the complexity of low complexity proteins
2020
Abstract There are multiple definitions for low complexity regions (LCRs) in protein sequences, with all of them broadly considering LCRs as regions with fewer amino acid types compared to an average composition. Following this view, LCRs can also be defined as regions showing composition bias. In this critical review, we focus on the definition of sequence complexity of LCRs and their connection with structure. We present statistics and methodological approaches that measure low complexity (LC) and related sequence properties. Composition bias is often associated with LC and disorder, but repeats, while compositionally biased, might also induce ordered structures. We illustrate this dichot…
The Conservation of Low Complexity Regions in Bacterial Proteins Depends on the Pathogenicity of the Strain and Subcellular Location of the Protein
2021
Low complexity regions (LCRs) in proteins are characterized by amino acid frequencies that differ from the average. These regions evolve faster and tend to be less conserved between homologs than globular domains. They are not common in bacteria, as compared to their prevalence in eukaryotes. Studying their conservation could help provide hypotheses about their function. To obtain the appropriate evolutionary focus for this rapidly evolving feature, here we study the conservation of LCRs in bacterial strains and compare their high variability to the closeness of the strains. For this, we selected 20 taxonomically diverse bacterial species and obtained the completely sequenced proteomes of t…

SummaryThis article examines the foundations of social experience from a psychoanalytic perspective. In current developmental psychology, social cognition debate, and phenomenology of empathy, it is widely assumed that the self and the other are differentiated from the outset, and the basic challenge is accordingly taken to consist in explaining how the gap between the self and the other can be bridged. By contrast, in the psychoanalytic tradition, the central task is considered to lie in explaining how such a gap is established in the first place. My article develops this latter idea. I focus on the infant’s early experience of care, show how the presence of the caregiver can be interprete…
The effect of perspective taking on the mediation process
2018
Stefano Boca, Maria Garro, Isabella Giammusso, Costanza Scaffidi Abbate Department of Psychology, University of Palermo, Palermo, Italy Background: Previous research demonstrated several benefits of strategic perspective taking in the field of intergroup relations and, more specifically, in the negotiation processes aimed at conflict resolution. The present study, which analyzes the effect of perspective taking and mediation in a conflict setting, corroborates the psychological models that hypothesize the positive effects of the assumption of the competitor’s perspective on having intergroup conflict and lessening of negative consequences. Materials and methods: After being involv…
Attentional biases to emotional scenes in schizophrenia: An eye-tracking study
2020
Attentional biases to emotional information may play a key role in the onset and course of schizophrenia. The aim of this experiment was to examine the attentional processing of four emotional scenes in competition (happy, neutral, sad, threatening) in 53 patients with schizophrenia and 51 controls. The eye movements were recorded in a 20-seconds free-viewing task. The results were: (i) patients showed increased attention on threatening scenes, compared to controls, in terms of attentional engagement and maintenance; (ii) patients payed less attention to happy scenes than controls, in terms of attentional maintenance; (iii) whereas positive symptoms were associated with a late avoidance of …
Benefit Incidence Analysis in Education
2007
07103; The standard benefit incidence algebra generally produces biased estimates of the distribution of public spending on education when students from poor and rich families are enrolled in schools that receive different levels of public spending per student. Except in very rare instances, removing these biases entails combining several sources of information in order to evaluate how unit spending varies across different population groups. Although such disaggregation is generally difficult to obtain, we show one way to overcome the data constraints that hinder a precise calculation of the incidence of public spending on education. The empirical example discussed in this article indicates…
Disclosure of duplicative studies: damned if you don't
2012
Duplicative publication requires duplicative editorializing. There are many forms of lesser redundancy such as unacknowledged secondary analyses of randomized clinical trials, fragmentation of studies with concurrent submission to various journals, and serial updating of observational studies. These practices result in publication bias. We have revised our instructions to authors to include disclosure of similar articles that are published, in press, or submitted to other journals to the editors upon submission.
