Browsing the information highway while driving: three in-vehicle touch screen scrolling methods and driver distraction
2012
Distraction effects of three alternative touch screen scrolling methods for searching music tracks on a mobile device were studied in a driving simulation experiment with 24 participants. Page-bypage scrolling methods with Buttons or Swipe that better facilitate resumption of visual search following interruptions were expected to lead to more consistent in-vehicle glance durations and thus, on less severe distraction effects than Kinetic scrolling. As predicted, Kinetic scrolling induced decreased visual sampling efficiency and increased visual load compared to Swipe, increased experienced workload compared to both Buttons and Swipe, as well as decreased lane keeping accuracy compared to ba…
Temperamentally inhibited children are at risk for poorer maths performance : self-concept as mediator
2020
AbstractIt has repeatedly been found that temperamental inhibition and low academic achievement are associated with each other: children with cautious and wary or shy behaviour are at risk for low academic achievement. Several suggestions about the mechanism behind this association have been made, these highlighting for example, the fewer learning opportunities of cautious and wary children and more negative interaction between teachers and inhibited children. However, the empirical studies about these mechanisms are rare and, thus, they have remained unclear. This study examined whether children’s maths-related self-concept of ability acts as a mediator between their temperamental inhibiti…
Passive sampling in monitoring of nonylphenol ethoxylates and nonylphenol in aquatic environments
2012
The present practices for determining the concentration levels of various pollutants are in many respects insufficient and for this reason, there is an urgent need especially to develop more cost-effective sampling methods. In this study, a novel passive sampling tool (the Chemcatcher®) for monitoring nonylphenol ethoxylates (NPEOs) and nonylphenol (NP) in aqueous media was tested. These environmentally harmful substances have been widely used in different household and industrial applications and they affect aquatic ecosystems, for example, by acting as endocrine disrupting compounds. The highest accumulation of NPEOs and NP in laboratory-scale tests was obtained when using an SDB-XC (stan…
Alliance portfolio diversity, organizational slack, and firm performance
2013
In this paper we analyze whether and how the availability of internal resources in the form of slack influences a firm ability to deal with partner diversity in its alliance portfolio. Alliances with diverse partners provide access to a broader pool of complementary resources, but they also entail significant coordination costs. In this context, we argue that slack acts as a doubleedged sword that can either facilitate or hinder the management of interdependencies among different alliance projects. Accordingly, we further argue that the net impact of slack will depend on the firm’s experience in dealing with the challenges posed by portfolio diversity. Empirical analysis on a sample of firm…
CHALLENGES TO MADE VALUES-BASED COMPETENCE MODEL FOR AMBULANCE PERSONNEL
2019
The purpose of this paper is to clarify and analyse the understanding of the values for Ambulance personnel, to compare and integrate it with the system of competencies used in the performance assessment and evaluation of professional competence. The results of State Emergency Medical Service ambulance personnel’s survey in the 2018 are analysed in the research. The results obtained Ambulance personnel’s different understanding of the importance of organization's values and its impact in management, staff attitude and work performance. The results of the survey have showed that Ambulance personnel has contradictive understanding of system of values. Their personal values are respect, compas…
Short-time non-work-related computing and creative performance
2014
It has been argued that non-work-related computing (NWRC) takes time away from work and, hence, decreases work productivity. On the other hand, it has also been claimed that short-time non-work-related computing (STNWRC) (a maximum of 15 minutes), has a positive impact on work productivity, including relief from boredom, higher creativity, and the underlying recovery mechanisms. To examine the impact of STNWRC on creative performance, we draw on Fredrickson's broaden-and-build theory, the concept of recovery with mental well-being and low cognitive effort. A 2 × 2 factorial experiment with 40 subjects was conducted. The results indicate that STNWRC has a positive effect on creative performa…
Is it still important to be light in ski jumping?
2019
In ski jumping low body weight development resulted in some serious underweight problems and therefore the International Ski Federation (FIS) decided to solve the problem by relating maximum ski length to Body Mass Index (BMI) in 2004. The present study examined the current relationship between body weight, ski length and performance (jumping distance) in ski jumping. By adopting the BMI regulation to specifications for competition equipment, the FIS succeeded in stopping the alarming development of underweight problems in ski jumping. However, as the results of the present study show, the BMI regulation adopted by the FIS has reduced the advantage of being light, but despite the use of sho…
Quantitative determination of casein genetic variants in goat milk: Application in Girgentana dairy goat breed
2016
The study was conducted to develop a high-performance liquid chromatographic (HPLC) method to quantify casein genetic variants (αs2-, β-, and κ-casein) in milk of homozygous individuals of Girgentana goat breed. For calibration experiments, pure genetic variants were extracted from individual milk samples of animals with known genotypes. The described HPLC approach was precise, accurate and highly suitable for quantification of goat casein genetic variants of homozygous individuals. The amount of each casein per allele was: αs2-casein A = 2.9 ± 0.8 g/L and F = 1.8 ± 0.4 g/L; β-casein C = 3.0 ± 0.8 g/L and C1 = 2.0 ± 0.7 g/L and κ-casein A = 1.6 ± 0.3 g/L and B = 1.1 ± 0.2 g/L. A good correl…
