Labor market performance of dropouts: the role of personality

2014

Purpose – The purpose of this paper is to provide evidence on labor market careers of dropouts with various levels of education. Design/methodology/approach – The paper compares the labor market careers of dropouts and non-dropouts between ages 15 and 50 by using longitudinal data. The paper analyses how the results change when the authors control for differences in personality characteristics. Findings – The paper finds that dropping out diminishes one's success in the labor market but this connection is reduced when the model is augmented with personality. Dropouts seem to have or lack certain personality characteristics that are associated with labor market success. These findings sugge…

Nonlinear evolution equations for turbulent superfluids

2010

In this paper a system of evolution equations for turbulent superfluid helium is written in the nonlinear regime, choosing as fundamental fields the density, the velocity, the heat flux, the non-equilibrium temperature and the average vortex line density per unit volume. Approximate equations are written, where second order terms in the non-equilibrium quantities are retained.

The two-fluid extended model of superfluid helium

2019

In this paper we perform the first numerical comparison between the two main existing models of superfluid helium: the two-fluid model proposed by Landau and the one-fluid extended model proposed from the extended thermodynamics. The numerical experiments in this paper regard the profiles of the so-called normal and superfluid components in 2D counterflow turbulence.

Gramatikas kļūdu analīze 12. klases angļu valodas eksāmena rakstiskajā daļā

2016

Angļu valodas centralizētais eksāmens 12. klasei sastāv no atsevišķām sadaļām katras valodas prasmes pārbaudei, bet rakstīšanas daļa sevī ietver vairāku prasmju pārbaudi. Rakstīšana un gramatika ir cieši saistītas. Šī pētījuma mērķis ir reģistrēt un klasificēt 12. klases skolēnu pieļautās gramatiskās kļūdas 2014. un 2015. gada centralizēto angļu valodas eksāmenu esejās. Diskursa analīze ir galvenā šī darba pētījuma metode. Pētījuma ietvaros tika analizētas simts esejas un noteiktas tajās esošās biežākās gramatiskās kļūdas un to cēloņi. Pētījuma rezultāti rāda, ka visbiežāk pieļautās gramatiskās kļūdas ir nepareizs artikulu lietojums, lietvārda un darbības vārda saskaņošana un nepareiza vārd…

Employee personal Internet usage in the workplace

2016

Information technology (IT) devices connected to the Internet, such as computers, tablets, and smartphones, have become pervasive in the workplace. These IT devices have greatly facilitated the performance of job tasks for employees. At the same time, employees are increasingly using these technologies for non-work-related purposes during office hours, which is called personal Internet usage in the workplace (PIU). Examples of PIU include, but are not limited to, checking and sending non-work-related emails, surfing news sites, visiting social network sites, e-banking, stock trading, and online shopping, chatting, and gaming. Previous studies on PIU present two schools of thought on PIU out…

Personal use of technology at work : a literature review and a theoretical model for understanding how it affects employee job performance

2021

Employee personal use of technology at work (PUTW)—defined as employees’ activities using organisational or personal IT resources for non-work-related purposes while at work—is increasingly common in organisations. Our review of existing PUTW studies (n = 137) suggests that previous studies widely discussed PUTW outcomes, antecedents, and policies. The literature review also indicates that previous studies have proposed opposing viewpoints regarding the effect of PUTW on employee job performance, but few studies offered empirical evidence. Consequently, the conditions under which PUTW can increase or decrease employee job performance have not been discussed. We develop a theoretical model (…

Ultraviolet A1 radiation induces nitric oxide synthase-2 expression in human skin endothelial cells in the absence of proinflammatory cytokines.

2001

Skin exposure to ultraviolet radiation from sunlight causes erythema and edema formation as well as inflammatory responses. As some of these ultraviolet-induced effects are potentially mediated by nitric oxide synthases, we examined the role of cytokines and ultraviolet A 1 radiation (340–400 nm) on the expression of the nitric oxide synthase-2 in endothelia of normal human skin biopsies during short-term organ culture as well as expression and activity of the nitric oxide synthase-2 in in vitro cell cultures of human dermal endothelial cells. Both, cytokine challenge (interleukin-1β + tumor necrosis factor-α + interferon-γ) but also ultraviolet A 1 exposure (50 J per cm 2 ) in the absence …
