Does Identity Precede Intimacy? Testing Erikson's Theory on Romantic Development in Emerging Adults of the 21st Century

Erikson stated that healthy identity development during adolescence is a precursor of intimacy in romantic relationships during emerging adulthood. However, from a developmental contextual perspective, there are reasons to question this strict developmental ordering. Using interview and questionnaire data from a longitudinal study on 93 adolescents, the authors tested whether ego development in middle adolescence predicts intimacy in emerging adulthood. Second, the authors examined whether identity achievement at the transition to adulthood mediates this link. Results revealed direct links between early ego development (age 15) and intimacy in romantic relationships (age 25). No paths were found from earlier intimacy to later ego development. No gender differences occurred. Relational identity achievement, an integrative identity construct measured at age 24, fully mediated the association between earlier ego development and later intimacy. This study confirms Erikson's old ideas on the developmental ordering of identity and intimacy for youngsters in the 21st century. Moreover, it highlights the integrative function of relational identity for later mature intimacy

Zu viel - zu früh? Zur Akzeleration im Jugendalter

Der vorliegende Beitrag beschäftigt sich mit aktuellen Trendveränderungen im Bereich der körperlichen Reife im Jugendalter. Er weist auf die zunehmende Akzeleration in der psycho-sozialen Reife sowie auf die Schwierigkeiten hin, die sich aus der erhöhten Reifegeschwindigkeit für die Bewältigung jugendtypischer "Entwicklungsaufgaben" ergeben. Obwohl Erwachsene oft meinen, Jugendliche würden sich "zu viel - zu früh" zumuten, gibt es doch Belege dafür, dass Jugendliche durchaus gegensteuern, wenn ihnen eine langsamere Entwicklung angemessener erscheint.

Effect of Co and Fe on the inverse magnetocaloric properties of Ni-Mn-Sn

At certain compositions Ni-Mn-$X$ Heusler alloys ($X$: group IIIA-VA elements) undergo martensitic transformations, and many of them exhibit inverse magnetocaloric effects. In alloys where $X$ is Sn, the isothermal entropy change is largest among the Heusler alloys, particularly in Ni$_{50}$Mn$_{37}$Sn$_{13}$ where it reaches a value of 20 Jkg$^{-1}$K$^{-1}$ for a field of 5T. We substitute Ni with Fe and Co in this alloy, each in amounts of 1 at% and 3 at% to perturb the electronic concentration and examine the resulting changes in the magnetocaloric properties. Increasing both Fe and Co concentrations causes the martensitic transition temperature to decrease, whereby the substitution by Co at both compositions or substituting 1 at% Fe leads to a decrease in the magnetocaloric effect. On the other hand, the magnetocaloric effect in the alloy with 3 at% Fe leads to an increase in the value of the entropy change to about 30 Jkg$^{-1}$K$^{-1}$ at 5T.Comment: 5 pages, 7 figures.

Tracheobronchial Manifestations of Aspergillus Infections

Human lungs are constantly exposed to a large number of Aspergillus spores which are present in ambient air. These spores are usually harmless to immunocompetent subjects but can produce a symptomatic disease in patients with impaired antifungal defense. In a small percentage of patients, the trachea and bronchi may be the main or even the sole site of Aspergillus infection. The clinical entities that may develop in tracheobronchial location include saprophytic, allergic and invasive diseases. Although this review is focused on invasive Aspergillus tracheobronchial infections, some aspects of allergic and saprophytic tracheobronchial diseases are also discussed in order to present the whole spectrum of tracheobronchial aspergillosis. To be consistent with clinical practice, an approach basing on specific conditions predisposing to invasive Aspergillus tracheobronchial infections is used to present the differences in the clinical course and prognosis of these infections. Thus, invasive or potentially invasive Aspergillus airway diseases are discussed separately in three groups of patients: (1) lung transplant recipients, (2) highly immunocompromised patients with hematologic malignancies and/or patients undergoing hematopoietic stem cell transplantation, and (3) the remaining, less severely immunocompromised patients or even immunocompetent subjects

Magnetization easy-axis in martensitic Heusler alloys estimated by strain measurements under magnetic-field

We study the temperature dependence of strain under constant magnetic-fields in Ni-Mn based ferromagnetic Heusler alloys in the form Ni-Mn-$X$ ($X$: Ga, In, Sn, Sb) which undergo a martensitic transformation. We discuss the influence of the applied magnetic-field on the nucleation of ferromagnetic martensite and extract information on the easy-axis of magnetization in the martensitic state.Comment: 3 pages, 3 figures.

The Association Between Parental Rearing Dimensions and Adolescent Psychopathology: A Cross-Cultural Study

Research on parental rearing dimensions faced ethnocentric criticism for mainly focusing on adolescents in Western industrialized countries. Over the past decade, the phenomenon of anxious parenting, so called “helicopter parenting”, gained attention in popular media as well as scholarly publications in addition to support and psychological control. Whether these parenting dimensions, which were associated with different health outcomes in adolescents, were only occurring in the Western world or are visible cross-culturally, has not been sufficiently studied. Therefore, it is unclear whether these links exist also for adolescents from other parts of the world. Additionally, the involvement of fathers in child rearing continues to be neglected in adolescent psychopathology research. The current cross-cultural study tested the association of maternal and paternal rearing dimensions with youth internalizing and externalizing psychopathology in a sample of 2415 adolescents (56% female, 15.33 years, SD = 0.61) from eight countries (Argentina, France, Germany, Greece, Pakistan, Peru, Poland, and Turkey). Hierarchical regression models showed that internalizing symptomatology was associated with mothers’ support, psychological control, and anxious rearing as well as fathers’ psychological control up and above predictors like country and mother’s level of education. For predicting externalizing symptomatology, mother’s anxious rearing, mother’s psychological control, and father’s support as well as father’s psychological control were significant up and above adolescents’ gender, standard of living, and country. To conclude, across countries, anxious rearing and psychological control experienced from both parents were substantially linked with adolescent mental health
