Cultural adaptation of a cognitive behavioral Internet intervention for the treatment of depression in Ecuador

2023

La depresión es un trastorno mental que puede limitar gravemente el funcionamiento cotidiano de las personas y también reducir la calidad de vida (Malhi y Mann, 2018). Su prevalencia es alta a nivel mundial y es una de las principales causas de discapacidad (WHO, 2017). Millones de personas padecen trastornos depresivos, afectando principalmente a adultos jóvenes en edad económicamente activa (PAHO, 2018). Los países de la región americana como Ecuador superan el 4% de prevalencia, lo que puede representar hasta el 10% de los años vividos con discapacidad (Kohn et al., 2018). Los efectos adversos de la depresión son complejos y pueden incluso llevar a desenlaces fatales como el suicidio, co…

Development and Preliminary Italian Validation of the Emergency Response and Psychological Adjustment Scale

2021

Evaluating the personal adaptation response to the emergency situations is very important for the prevention of mental distress, for the activation of network and community synergies and for the planning and implementation of appropriate psycho-social interventions. So far there are no short tools for the overall assessment of cognitive, emotional and behavioral responses of psychological adaptation to the emergency in the psychometric panorama. The Emergency Response and Psychological Adjustment Scale (ERPAS) was administered to a sample of 1,088 participants, while the concurrent validity was tested through a second administration to 600 participants along with the GSE (Generalized Self-E…

Nonlinear Time-Series Adaptation for Land Cover Classification

2017

Automatic land cover classification from satellite image time series is of paramount relevance to assess vegetation and crop status, with important implications in agriculture, biofuels, and food. However, due to the high cost and human resources needed to characterize and classify land cover through field campaigns, a recurrent limiting factor is the lack of available labeled data. On top of this, the biophysical–geophysical variables exhibit particular temporal structures that need to be exploited. Land cover classification based on image time series is very complex because of the data manifold distortions through time. We propose the use of the kernel manifold alignment (KEMA) method for…

Respostas e adaptações de comunidades de colêmbolos (Hexapoda: Collembola) a condições de inundação e hipoxia

2009

Standard ecological methods (pitfall traps, trunk eclectors and soil cores) were used to evaluate collembolan community responses to different flooding intensities. Three sites of a floodplain habitat near Mainz, Germany, with different flooding regimes were investigated. The structures of collembolan communities are markedly different depending on flooding intensity. Sites more affected by flooding are dominated by hygrophilic and hygrotolerant species, whereas the hardwood floodplain is dominated by mesophilic species. The survival strategies of the hygrophilic and hygrotolerant species include egg diapause and passive drifting. The physiological adaptations to hypoxic conditions of sever…

Evolutionary genomics can improve prediction of species' responses to climate change

2020

Abstract Global climate change (GCC) increasingly threatens biodiversity through the loss of species, and the transformation of entire ecosystems. Many species are challenged by the pace of GCC because they might not be able to respond fast enough to changing biotic and abiotic conditions. Species can respond either by shifting their range, or by persisting in their local habitat. If populations persist, they can tolerate climatic changes through phenotypic plasticity, or genetically adapt to changing conditions depending on their genetic variability and census population size to allow for de novo mutations. Otherwise, populations will experience demographic collapses and species may go ext…

The role of local adaptation in the relationship between an endangered root hemiparasite Euphrasia rostkoviana, and its host, Agrostis capillaris

1999

We experimentally studied the role of local adaptation and the co-evolutionary relationship between an annual, endangered root hemiparasite Euphrasia rostkoviana and its main host Agrostis capillaris. According to our hypothesis, the existence of local adaptation in hemiparasites should be observable in better hemiparasite performance when attached to A. capillaris hosts originating from Euphrasia populations. After one month of growth, the height and the number of leaves of hemiparasites were not affected by the origin of their hosts. The differences in growth were due to between population effects. The situation remained constant after three months. Hemiparasite biomass was not affected b…

Population structure of a parasitic plant and its perennial host

2002

Characterization of host and parasite population genetic structure and estimation of gene flow among populations are essential for the understanding of parasite local adaptation and coevolutionary interactions between hosts and parasites. We examined two aspects of population structure in a parasitic plant, the greater dodder (Cuscuta europaea) and its host plant, the stinging nettle (Urtica dioica), using allozyme data from 12 host and eight parasite populations. First, we examined whether hosts exposed to parasitism in the past contain higher levels of genetic variation. Second, we examined whether host and parasite populations differ in terms of population structure and if their populati…

Assessment of Organizational Trust: Preliminary Data for Romanian Adaptation of the Organizational Trust Inventory Short Form

2013

Abstract In the last years, trust became an important variable in regard to the well-being of organizations. In Romania, it was included in studies as a variable but there are few instruments that measure organizational trust. Therefore I identify a necessity for developing instruments useful in assessing and promoting any organizational adjustments. This paper presents the preliminary data obtained in the process of adaptation of OTI for the Romanian population. In doing so, we followed the guidelines of ITC. Using a sample of 108 employees the psychometric results show that OTI-RO has a high level of internal consistency reliability (a = 0.94) and it can be used exclusive for equivalent p…

Selection on life-history traits and genetic population divergence in rotifers

2009

A combination of founder effects and local adaptation – the Monopolization hypothesis – has been proposed to reconcile the strong population differentiation of zooplankton dwelling in ponds and lakes and their high dispersal abilities. The role genetic drift plays in genetic differentiation of zooplankton is well documented, but the impact of natural selection has received less attention. Here, we compare differentiation in neutral genetic markers (FST) and in quantitative traits (QST) in six natural populations of the rotifer Brachionus plicatilis to assess the importance of natural selection in explaining genetic differentiation of life-history traits. Five life-history traits were measur…
