Adult attachment insecurity and dyadic adjustment: The mediating role of self-criticism

Although it is well established that adult attachment is associated with relationship quality, the mechanisms involved in this association are still poorly understood. Individual variables that are shaped in early attachment experiences, such as self-criticism, may be particularly important. The present study aimed to investigate the mediating role of self-criticism and self-reassurance on the association between attachment-related anxiety and avoidance and dyadic adjustment

Adult Attachment and Dyadic Adjustment: The Mediating Role of Shame

Although it is widely recognized that adult attachment is associated with romantic relationship quality, the mechanisms involved remain poorly understood. This study aimed to investigate the mediating role of external and internal shame on the association between attachment and dyadic adjustment. A battery of self-report measures was completed by 228 Portuguese participants and a serial multiple mediation model was tested. Data showed that, in the population under study, attachment dimensions were associated with worse dyadic adjustment through high external and internal shame. Internal shame alone also mediated the association between attachment avoidance and dyadic adjustment. This study identifies a new putative mechanism linking adult attachment and intimate relationship functioning that may be targeted in couples therapy to promote a better dyadic adjustment and relationship functioning

Emplacement of the Lavadores granite (NW Portugal): U/Pb and AMS results

Studies of Anisotropy of Magnetic Susceptibility (AMS) and U-Pb geochronology, in zircon fractions, were carried out in a magnetite type-granite, the Lavadores granite, which is an example of a late to post-orogenic Variscan granite in northern Portugal (NW Iberian Peninsula). The U-Pb zircon analyses yield an age of 298 +/- 11 Ma that is considered to be the emplacement age of this granite and thus suggesting a post-tectonic emplacement. This is also supported by the magmatic nature of the microstructures. Magnetic lineations are subvertical and magnetic foliations display a general WNW-ESE subvertical pattern consistent with a dextral kinematic. These AMS data suggest that the emplacement of the Lavadores granite was controlled by a major mechanical anisotropy formed by transtensional structures associated with the Porto-Tomar shear zone

Late-Variscan emplacement and genesis of the Vieira do Minho composite pluton, Central Iberian Zone: Constraints from U-Pb zircon geochronology, AMS data and Sr-Nd-O isotope geochemistry

In the Central Iberian Zone synorogenic (syn- and late-D-3, the last deformation phase) composite batholiths of biotite-rich granitods with peraluminous character are well represented. We report here U-Pb zircon and monazite ages, geochemical, Sr-Nd-O isotopic data and Anisotropy of Magnetic Susceptibility (AMS) studies for the late-D-3 Vieira do Minho pluton, in northern Portugal. AMS reveals the paramagnetic behaviour of these granites and the magnetic fabric enhances the major role of NW-SE regional anisotropies on controlling the ascent and emplacement of the magmas. Magnetic anisotropy and medium temperature microstructures also point out the evolution of regional tectonics during crystallization of the magma. U-Pb zircon and monazite analyses yield consistent ages of 310 +/- 2 Ma and 312 +/- 2 Ma, interpreted as emplacement age. The Vieira do Minho pluton consists of two peraluminous monzogranites, the VMG and the MRG. Both have similar epsilon(Nd) values (VMG= -52 to -5.7; MRG= -4.98 to -5.96) but the VMG is slightly enriched in Sr-87/(86)(i)=0.7087-0.7098 as well as in delta O-18 in the range of 10.6 parts per thousand to 11.0 parts per thousand than the MRG with Sr-87/(86)(i)=0.7064-0.7075 and delta O-18=9.9 parts per thousand-10.5 parts per thousand. These granites are associated with coeval scarce grabroic intrusions and/or mafic microgranular enclaves which are not considered as mafic precursors of the associated granitic magmatism. Instead, a lower metaigneous crustal source, at different levels, is proposed based on the available data set

Empathy and Coping in Allied Health Sciences: Gender Patterns

This cross-sectional study is part of a larger longitudinal study conducted in an Allied Health Sciences School. Participants were 183 undergraduate students from 12 training programs (e.g., Physiotherapy, Occupational Therapy, Speech Therapy). info:eu-repo/semantics/publishedVersio

Lower on the totem pole : The influence of sense of control and trait anxiety on cortisol at lower hierarchical levels

Several studies have found that hierarchical position either increases or reduces physiological stress. The purpose of this study was to investigate the moderating effect of sense of control or trait anxiety on the relationship between hierarchical position and physiological stress. Using a multilevel mixed-effects regression, we hypothesized that sense of control or trait anxiety could be buffers (accelerants) in lowering (increasing) physiological stress for those higher (lower) in the hierarchy. We draw on a sample of 202 Portuguese executives. Our findings indicate that relative to top-level managers, those lower in the hierarchical position had a lower salivary cortisol. Considering the moderating effects of sense of control or trait anxiety, executives lower in the hierarchy who have a higher sense of control or report higher trait anxiety levels had higher cortisol levels. Sense of control or trait anxiety may aid in the understanding of more subtle associations between hierarchical position and physiological stress.info:eu-repo/semantics/publishedVersio

Chitosan scaffolds incorporating lysozyme into CaP coatings produced by a biomimetic route : a novel concept for tissue engineering combining a self-regulated degradation system with in situ pore formation

This study describes an innovative self-regulated degrading material with gradual in situ pore formation ability for bone tissue engineering applications. This approach is based on the incorporation of the lysozyme enzyme into calcium phosphate (CaP) coatings, prepared on the surface of chitosan scaffolds by means of a biomimetic coating technique with the aim of controlling their degradation rate and subsequent formation of pores. However, because lysozyme has antibacterial properties, these coatings may act as a carrier for its sustained release, preventing infection upon implantation. In order to prove the concept of in situ pore formation, the coated scaffolds (with and without lysozyme) were incubated in two different solutions at different pH to simulate normal physiological conditions (pH 7.4) and inflammatory response (pH 5). The weight loss and morphology of the scaffolds was monitored over time. At pH 7.4, the scaffolds remained more stable than at pH 5. The scaffolds incubated at pH 5 showed a rapid decrease in their initial weight, and scanning electron microscopy imaging revealed the formation of a highly porous structure. Furthermore, evaluation of the activity of the incorporated lysozyme revealed that the enzyme was able to hydrolyse the peptidoglycan of the bacteria cell walls (as detected by the decrease in optical density with time), indicating that the enzyme remained active after being incorporated into the CaP coating.This work was supported by the European NoE EXPERTISSUES (NMP3-CT-2004-500283), the European STREP HIPPOCRATES (NMP3-CT-2003-505758), the Portuguese Foundation for Science and Technology (FCT) through POCTI and/or FEDER programmes

Application of edible alginate films with pineapple peel active compounds on beef meat preservation

Alginate-based edible films containing natural antioxidants from pineapple peel were applied in the microbial spoilage control, color preservation, and barrier to lipid oxidation of beef steaks under storage at 4 C for five days. Di erent stabilization methods of pineapple peel compounds were used before incorporation into alginate films, including extracted compounds with an hydroalcoholic solvent encapsulated in microparticles, microparticles produced by spray-drying pineapple peel juice, and particles obtained by milling freeze dried pineapple peel. Bioactive films exhibited higher antioxidant activity (between 0.15 mol to 0.35 mol FeSO4.7H2O/g dried film) than the alginate film without these compounds (0.02 mol FeSO4.7H2O/g dried film). Results showed that control films without active compounds had no significant e ect on decreasing the microbial load of aerobic mesophilic and Pseudomonas spp., while the films containing encapsulated hydroalcoholic extract showed a significant inhibitory e ect on microbial growth of meat at two days of storage. Alginate films containing peel encapsulated extract were e ective for maintaining the color hue and intensity of red beef meat samples. Pineapple peel antioxidants have the potential to retard lipid oxidation in meat samples, and the possibility of incorporation of a higher amount of pineapple peel bioactive compounds in the films should be investigatedinfo:eu-repo/semantics/publishedVersio

Assessment of sediment contamination in an impacted estuary: differential effects and adaptations of sentinel organisms and implications for biomonitoring

Conferência realizada em Lisboa, de 6-9 November de 2013Estuarine pollution is reflected in the concentration of toxicants in sediments, depending on their geochemical properties, since sediments trap substances from the water column, either dissolved or bound to suspended matter. However, determining risk of sediment contaminants to biota has many constraints. For such reason, integrative approaches are keystone. Taking the Sado estuary (SW Portugal) as a case study, contrasted to a reference estuary (the Mira) within the same geographical location, the present study aimed at integrating sediment contamination with the effects and responses to pollutants in distinct benthic organisms with commercial and ecological value
