In-pair divestment
Full text linkHow do in-pair obstacles and difficulties affect the intensity of love? Why do people at some point in their romantic relationships emotionally disinvest? Does a reduction in the intensity of romantic feelings always result in relationship breakup? Core assumptions of emotional intensity theory suggest that feelings of love vary in strength according to an adaptive “energy conservation” principle. To save energy, romantic partners automatically adapt the intensity of their feelings to the minimum level needed to overcome the obstacles and difficulties the couple encounters daily (e.g., reciprocal partners’ flaws, relational stress, and perceived risk of breakup), because small relationship obstacles and difficulties only demand the investment of correspondingly small quantities of motivational/emotional resources to be surmounted. Thus, romantic feelings appear to diminish when obstacles are almost absent and, by contrast, to augment when obstacles grow stronger—with emotional strength reflecting the magnitude of what challenges the stability of the relationship. This specific fine-tuning of emotion intensity holds up, however, only to the point where maintaining the relationship is still worth the effort. Beyond this point, actual in-pair divestment occurs, because any further investment of energy would represent a useless (i.e., nonfunctional) waste of energy. In adopting the perspective of emotional intensity theory, this chapter reviews the most relevant empirical evidence on romantic relationships in light of a unitary, single-process explanation that reconciles past conflicting findings while also addressing new theoretical and practical implications for contemporary romantic partnerships

No full textStimulation of antibody response in the gastro-intestinal mucosa of immunodeficient mice by oral treatment with bacterial antigens. An immunoperoxidase study
No full textThe immunodeficient (nude) mice were chosen as a model to verify the in vivo stimulating activity of bacterial antigens on the humoral immune response. By using an immunoperoxidase technique, the Ig+ cell content in the gastro-intestinal mucosa of mice was evaluated after oral treatment with a mixture of bacterial antigen fractions (trade name Colopten). Treatment for 15 days was able to induce a significant increase in the proportions of Ig+ cells in both the jejunum and ileum. In contrast, the number of Ig+ cells was significantly increased after 30 days of treatment throughout the gastro-intestinal tract. Based on the staining intensity, a semiquantitative evaluation of the Ig content of the cells was made. Strongly stained Ig+ cells were localized into the gastro-intestinal mucosa during treatment and appeared to be the prominent lymphoid cell population in the small bowel after prolonged administration of Colopten. The morphological analysis of tissues showed that after treatment Ig+ cells tended to be collected within the mucosa rather than being isolated as in untreated animals. Therefore, these results demonstrate that oral administration of Colopten was able to elicit a local humoral immune response in an animal model for severe immunodeficiency
Do Feelings of Loneliness Mediate the Relationship between Sociocognitive Understanding and Depressive Symptoms During Late Childhood and Early Adolescence?
No full textAn interesting association between sociocognitive understanding and depression has been documented in clinical populations, with high levels of depression apparently related to theory-of-mind deficits. Yet no research has so far investigated this relationship among typically developing preadolescents. Therefore, the authors' main aim was to extend previous findings to the general population and to a younger age group. A secondary aim was to explore the role of feelings of loneliness referring to the previous link. A sociocognitive understanding task followed by self-report questionnaires on depressive symptoms and perceived loneliness were administered to a sample of 326 students attending primary and middle schools. Mediation analyses revealed that feelings of loneliness mediated the effect of sociocognitive understanding on depressive symptoms, but only among girls. In boys, depressive symptoms were directly linked to sociocognitive skills. In girls, on the contrary, the relationship between sociocognitive skills and depressive symptoms was significantly mediated by feelings of loneliness. Theoretical and practical implications of these findings are discussed
Monitoring Elastic Parameters Changes during Underground Hydrogen Storage Using Rock Physics Parametrized FWI
No full textSeasonal storage of hydrogen produced from renewable energy can become one of the key strategies tomeet the high energy demand of today’s society. The most suitable sites for seasonal hydrogen storageare depleted gas fields. This study proposes a workflow based on the integration of full-waveforminversion (FWI), rock physics modeling (RPM) and gas property modeling for monitoring changes inelastic medium parameters due to hydrogen injection. A rock physics model including the Gassmannequation and fluid mixing laws has been implemented, which accurately links rock physical propertiesto elastic properties. The parameterized approach is based on optimizing fluid saturation to reducecrosstalk between model parameters during the inversion process, while simultaneously providing aquantitative estimation of the fluid within the reservoir. The synthetic models show that parameterizedinversion produces higher accuracy and fewer artifacts than conventional FWI. Our results underscorethe importance of an appropriate RPM to reflect real subsurface conditions and proper fluid mixinglaws. Therefore, FWI parameterization provides an efficient technique for monitoring hydrogen storagesites in depleted gas fields to ensure efficient storage
