Work-life Balance Decision-making of Norwegian Students: Implications for Human Resources Management

2016

Objective : The paper aims at identifying and assessing the significance of work-life balance determinants between the Youth of highly developed societies and its implications for human resources management on the example of Norway. Research Design & Methods : The research target group consists of 236 respondents recruited among Norwegian tertiary education students. It employed literature analysis, two-stage exploratory research: direct individual in-depth interviews, survey based on a self-administered, web-based questionnaire with single-answer, limited choice qualitative & quantitative, as well as explanatory research (informal moderated group discussions). Findings: The research on per…

Prospective elementary teachers’ perceptions of the processes of modeling: A case study

2012

In this paper we discuss a study on the approaches to modeling of students of the 4-year elementary school teacher program at the University of Palermo, Italy. The answers to a specially designed questionnaire are analyzed on the basis of an a priori analysis made using a general scheme of reference on the epistemology of mathematics and physics. The study is performed by using quantitative data analysis methods, i.e. factorial analysis of the correspondences and implicative analysis. A qualitative analysis of key words and terms used by students during interviews is also used to examine some aspects that emerged from the quantitative analysis. The students have been classified on the basis…

A quantitative insight into the impact and performance of seed accelerators and their accelerated start-ups

2020

El tema de investigación de esta tesis es el estudio de las aceleradoras de emprendimiento (AE), consideradas la nueva generación de incubadora de empresas (Bøllingtoft, 2012). Tanto las incubadoras como las aceleradoras permiten a las empresas jóvenes comenzar su actividad a través de un proceso de aprendizaje, consultoría e inversión, con el objetivo de aumentar sus posibilidades de supervivencia y crecimiento en el mercado durante sus primeros meses de vida (Cohen y Hochberg, 2014). El número de AE ha aumentado drásticamente desde la primera Aceleradora conocida en 2005 (Y Combinator), hasta un estimado de más de 3.000 AE en todo el mundo (Hochberg, 2016). Europa en particular, experimen…

Water Fluxes in Polymeric Membranes for Desalination via Membrane Distillation

2010

Membrane distillation is an emerging technique for seawater desalination. Hydrophobic polymeric membranes are used to separate the solute‐free water vapour from the hot solution. Vapour fluxes of commercial polymeric membranes were measured in various conditions, i.e. natural and forced convection and vacuum. Vapour fluxes were also predicted with models and compared with experimentals. Higher fluxes were recorded in vacuum conditions.

Dose calculation in biological samples in a mixed neutron-gamma field at the TRIGA reactor of the University of Mainz

2010

To establish Boron Neutron Capture Therapy (BNCT) for non-resectable liver metastases and for in vitro experiments at the TRIGA Mark II reactor at the University of Mainz, Germany, it is necessary to have a reliable dose monitoring system. The in vitro experiments are used to determine the relative biological effectiveness (RBE) of liver and cancer cells in our mixed neutron and gamma fi eld. We work with alanine detectors in combination with Monte Carlo simulations, where we can measure and characterize the dose. To verify our calculations we perform neutron fl ux measurements using gold foil activation and pin-diodes . Material and methods . When L- α -alanine is irradiated with ionizing …

Bis[S-hexyl 3-(thiophen-2-ylmethylidene)dithiocarbazato-κ2N3,S]palladium(II)

2016

In the title complex, [Pd(C12H17N2S3)2], the PdIIatom exhibits a square-planar coordination geometry with theN,S-chelating ligands arranged in atransconfiguration. Intramolecular C—H...S hydrogen bonds are observed. In the crystal, molecules are linked by weak C—H...N hydrogen-bond interactions, forming chains parallel to thebaxis.

The dynamics of adsorption and desorption of gaseous molecules on the external surface of a crystal and a membrane of zeolite silicate-1 is investigated by molecular dynamics simulation. The gases ...

Monte Carlo Simulations of Parallel Charged Platelets as an Approach to Tactoid Formation in Clay

2013

The free energy of interaction between parallel charged platelets with divalent counterions has been calculated using Monte Carlo simulations to investigate the electrostatic effects on aggregation. The platelets are primarily intended to represent clay particles. With divalent counterions, the free energy for two platelets or two tactoids (clusters of parallel platelets) shows a minimum at a short separation due to the attraction caused by ion-ion correlations. In a salt-free system, the free energy of interaction has a long-range repulsive tail beyond the minimum. The repulsion increases for tactoids with larger aggregation numbers, whereas the depth of the free-energy minimum is graduall…
