Identity Development in Adulthood: Introduction
2016
In line with Erikson’s suggestions, increasing empirical evidence substantiates that considerable identity development takes place over the course of adulthood. What then does identity development during adulthood entail? The key findings of adult identity formation from four culturally different countries, and the challenges of analyzing the complex concept of identity are discussed. Although a wide array of identity measures are available, they have not been sufficiently validated for use with middle-aged or older adults. Additionally, different measures may yield results that are not comparable across studies. More studies are needed on adult identity development in populations represent…
Microscopic Insights Into the Formation of Methanesulfonic Acid–Methylamine–Ammonia Particles Under Acid-Rich Conditions
2022
Understanding the microscopic mechanisms of new particle formation under acid-rich conditions is of significance in atmospheric science. Using quantum chemistry calculations, we investigated the microscopic formation mechanism of methanesulfonic acid (MSA)–methylamine (MA)–ammonia (NH3) clusters. We focused on the binary (MSA)2n-(MA)n and ternary (MSA)3n-(MA)n-(NH3)n, (n = 1–4) systems which contain more acid than base molecules. We found that the lowest-energy isomers in each system possess considerable thermodynamic and dynamic stabilities. In studied cluster structures, all bases are protonated, and they form stable ion pairs with MSA, which contribute to the charge transfer and the stab…
Identity Processes in Adulthood: Diverging Domains
2005
Patterns of identity formation were analyzed in a longitudinal framework, from ages 27 to 36 and then to 42 years of age. Information from all 3 ages was available for 197 participants (100 women, 97 men). A variation of Marcia’s (1966) Identity Status Interview included 5 domains: religious beliefs, political identity, occupational career, intimate relationships, and lifestyle. Great variability in identity status assessments was found across the domains at each age level. The domains representing work and family (occupation, relationships, and lifestyle) were more salient for middle- aged adults than were ideological domains (religion and politics). Development along the hypothesized sequ…
Field-Specific Educational Practices as a Source for Students' Vocational Identity Formation
2008
Although work-related identity research has undergone considerable expansion in recent years, vocational identity among students remains a neglected area. However, initial vocational education plays a crucial role in the process of lifelong learning. Accordingly, this chapter discusses students' vocational identity formation during their vocational education and training. As recent findings on vocational or professional identity emphasise its context-based or sociocultural construction, [the authors] examined students' vocational identity formation in two different fields: one) technology and transport, and two) social services and health care. [The authors'] quantitative data indicate that…
Double-application of platelet-rich plasma on bone healing in rabbits
2010
Objective: Platelet-rich plasma (PRP) is considered to enhance bone formation especially at early stages of wound healing, depending on the limited and short life-span of platelets and growth factors. The aim of this study was to evaluate efficacy of double-application of PRP (DA-PRP) on bone healing in a rabbit calvarial defect model. Study design: Twenty-eight rabbits, each had two surgically prepared calvarial bone defects (10mm diameter), were included in this study and randomly divided into six groups. Defects (n=56) were treated with single-application of PRP (SA-PRP)(n=10), SA-PRP and beta-tricalciumphosphate (SA-PRP+TCP)(n=10), DA-PRP (n=8), DA-PRP and beta-tricalciumphosphate (DA-P…
Oxidation Processes in Sicilian Olive Oils Investigated by a Combination of Optical and EPR Spectroscopy
2012
: Extra virgin olive oil (EVOO) is recognized as one of the healthiest foods for its high content of antioxidants, which forestall and slow down radical formation. Free radical-initiated oxidation is considered one of the main causes of rancidity in fats and oils. As a consequence, reliable protocols for the investigation of oil oxidation based on selective, noninvasive, and fast methods are highly desirable. Here we report an experimental approach based on UV-Vis absorbance, steady-state fluorescence, and electron paramagnetic resonance (EPR) spectroscopy for studying oxidation processes induced by temperature for a period up to 35 d on Sicilian EVOO samples. We followed the decrease in β…
Il corpo e l'arte come risorsa formativa all'Università:un percorso attraverso la danza-movimento terapia per futuri formatori
2015
The body and the Art as formative resources at University: a path through the dance-movement therapy for future educators Based on a personal experience of workshop with university master's students for over ten years, the article shows how a dance-movement therapy course can quickly open up new existential perspectives, enabling new narrative about one’s relationship with the world and increasing reflexive capacity and self-awareness. The students seem to find a way for integrating different parts of themselves, for accepting their difficulties and weaknesses, for reflecting and developing deep contacts, overcoming insecurity and discovering their value and their own creative abilities.
The Gaia-ESO Survey: The origin and evolution of s-process elements
2018
Context. Several works have found an increase of the abundances of the s-process neutron-capture elements in the youngest Galactic stellar populations. These trends provide important constraints on stellar and Galactic evolution and they need to be confirmed with large and statistically significant samples of stars spanning wide age and distance intervals. Aims. We aim to trace the abundance patterns and the time evolution of five s-process elements - two belonging to the first peak, Y and Zr, and three belonging to the second peak, Ba, La, and Ce - using the Gaia-ESO IDR5 results for open clusters and disc stars. Methods. From the UVES spectra of cluster member stars, we determined the ave…
The Gaia-ESO Survey : Probes of the inner disk abundance gradient
2016
The nature of the metallicity gradient inside the solar circle (R_GC < 8 kpc) is poorly understood, but studies of Cepheids and a small sample of open clusters suggest that it steepens in the inner disk. We investigate the metallicity gradient of the inner disk using a sample of inner disk open clusters that is three times larger than has previously been studied in the literature to better characterize the gradient in this part of the disk. We used the Gaia-ESO Survey (GES) [Fe/H] values and stellar parameters for stars in 12 open clusters in the inner disk from GES-UVES data. Cluster mean [Fe/H] values were determined based on a membership analysis for each cluster. Where necessary, dis…
Gaia-ESO Survey: Global properties of clusters Trumpler 14 and 16 in the Carina nebula
2017
Aims: We present the first extensive spectroscopic study of the global population in star clusters Trumpler 16, Trumpler 14, and Collinder 232 in the Carina nebula, using data from the Gaia-ESO Survey, down to solar-mass stars. Methods: In addition to the standard homogeneous survey data reduction, a special processing was applied here because of the bright nebulosity surrounding Carina stars. Results: We find about 400 good candidate members ranging from OB types down to slightly subsolar masses. About 100 heavily reddened early-type Carina members found here were previously unrecognized or poorly classified, including two candidate O stars and several candidate Herbig Ae/Be stars. Their l…
