Unpacking the link between family socioeconomic status and civic engagement during the transition to adulthood: Do work values play a role?

2017

We investigated whether the link between family-of-origin socioeconomic status (SES) and civic engagement in young adulthood is mediated by youth’s work values, i.e., the desired characteristics of their current or future jobs. We used data from a Finnish study: 2004 (age 16–18, NT1 = 1,301); 2011 (age 23–25, N T2 = 1,096); and 2014 (age 25–27, NT3 = 1,138). A lower family SES in 2004 was negatively related to youth’s civic engagement in 2014. Lower family SES predicted the importance that youth attached to extrinsic job rewards (e.g., good pay) in 2011, but not the importance of intrinsic job rewards (e.g., learning opportunities). Extrinsic work values, in turn, predicted lower civic enga…

The development of work values during the transition to adulthood : A two-country study

2017

This study addresses the development of work values—the desired characteristics of one's current or future job—during young adulthood. Using two panel studies from Germany (N = 2506) and Finland (N = 1326), we investigated (a) mean-level and rank-order change and stability in work values across three biennial waves (age 20/21 to age 25/26); and (b) the influence of stable background characteristics as well as of major transitions in family and work roles on inter-individual differences and intra-individual changes in work values. Latent measurement models with three work value dimensions showed good fit in both countries: extrinsic (importance of job security and material rewards), intrinsi…

A first-order phase transition for pulsar surface

2012

In this paper, we explain the existence of a possible first-order phase transition that may occur over the external solid crust of a pulsar, by means of an interpretation of a particular formal model (drawn from Theoretical Astrophysics) whose thermodynamical phenomenology shows a possible first-order phase transition (according to Landau’s Phenomenological Theory).

Preparation, crystal structure at 298 and 90 K and phase transition in (C2H5NH3) 2[SbBr5] studied by the single crystal X-Ray diffraction method

2004

The reaction of antimony(III) oxide with ethylamine, in molar ratios from 1:1 to 1:10, in concentrated hydrobromic acid leads to the formation of one product – bis(ethylammonium) pentabromoantimonate(III). The structure of (C2H5NH3)2[SbBr5] was determined at 298 and 90 K, below and above the phase transition that occurs at about 158.5 K. The orthorhombic system was found in both phases, space groups Cmca and Pbca at 298 and 90 K, respectively. At both temperatures the structure consists of [SbBr6] 3− octahedra connected via cis bromine atoms forming one-dimensional zig-zag [{SbBr5}2−]n chains. The ethylammonium cations fill the space between polyanionic chains. The organic and inorganic sub…

Darbības vārdu savienojumi ar postpozīcijām veidi rakstos par jaunuzņēmumiem

2019

Ziņu portāli ir vieni no izplatītākajiem informācijas avotiem, kuri informē par jaunākajām aktualitātēm pasaulē. Attiecīgi, ir ļoti svarīgi apzināt valodas lietojumu un tās atspoguļojumu ziņu rakstos. Tādēļ šī pētījuma mērķis ir pētīt valodas lietojumu rakstos par jaunuzņēmumiem, precīzāk, darbības vārdus ar postpozīcijām un to semantiskās un sintaktiskās īpašības. Lai sasniegtu mērķi, pētījums balstās uz 30 ziņu rakstiem par jaunuzņēmumiem, pēta 220 darbības vārdus ar pospozīcijām un to pielietojumu. Teorētiskā literatūra atklāja ka darbības vārdi ar postpozīcijām ir komplicēti to pārnesto nozīmju un gramatisko īpašību dēļ. Pētījuma rezultāti atspoguļo visbiežāk izmantotos darbības vārdus …

Aluminum tri-isopropoxide as an alternative precursor for atomic layer deposition of aluminum oxide thin films

2019

Due to the safety challenges associated with the use of trimethylaluminum as a metal precursor for the deposition of alumina, different chemicals have been investigated over the years to replace it. The authors have investigated the use of aluminum tri-isopropoxide (TIPA) as an alternative alkoxide precursor for the safe and cost-effective deposition of alumina. In this work, TIPA is used as a stable Al source for atomic layer deposition (ALD) of Al2O3 when different oxidizing agents including water, oxygen plasma, water plasma, and ozone are employed. The authors have explored the deposition of Al2O3 using TIPA in ALD systems operating in vacuum and atmospheric pressure conditions. For the…

Toward Sustainable PLA-Based Multilayer Complexes with Improved Barrier Properties

2019

Poly(lactic acid) or PLA is currently considered as one of the most promising substitutes of conventional plastics, with low environmental impact, especially for food packaging applications. Nevertheless, some drawbacks, such as high permeability to oxygen, are still limiting its industrial applications. The objective of this study was to highly increase the oxygen barrier performance of PLA without compromising its sustainable nature and following the principles of circular economy perspective. Coproducts coming from mill industries, such as wheat gluten proteins (WG), were used to produce PLA-WG-PLA multilayer complexes with improved barrier performance. Different technologies of industri…
