Diferencēts mācību process matemātikā 7. klasē
2022
Skolēni ir atšķirīgi viens no otra, un dažādi ir veidi, kā viņi vislabāk apgūst mācību saturu. Skolotāji diezgan bieži saskaras ar “sliktu” uzvedību klasē, vai skolēnu neieinteresētību un neiesaistīšanos mācību darbā, un viens no galvenajiem iemesliem daudzkārt ir neveiksmīgi izvēlētas mācību metodes un vienveidīgi izplānota mācību stunda. Šajā darbā ir apskatīta diferenciācijas pieeja, tās ieviešana mācību stundās, un kāda ir skolēnu iesaiste un aktivitāte, diferencējot mācību procesu. Šī darba mērķis ir pētīt un analizēt diferenciāciju un tās ietekmi uz katra skolēna mācīšanos matemātikas stundās. Pētījuma rezultāti: Tika izpētīta diferenciācija, un tās ietekme uz skolēniem. Aptaujas rezu…
Regulation of hdc expression and HDC activity by enological factors in lactic acid bacteria.
2008
Aims: The aim of this work was to study the influence of enological factors on the histidine decarboxylase gene (hdc) expression and on histidine decarboxylase enzyme (HDC) activity in Lactobacillus hilgardii, Pediococcus parvulus and Oenococcus oeni. Methods and Results: Cell extracts and whole cells were used. Glucose, fructose, malic acid and citric acid diminished the hdc expression. Ethanol did not increase hdc expression or activity in cells, but increased HDC activity. Temperature and pH had effect on the activity of HDC but not on hdc expression. Tartaric acid and l-lactic acid, and sulphur dioxide (SO2) had no effect on enzyme synthesis and activity. Bacterial species differ in t…
Antibacterial activity and cytotoxicity of selected Egyptian medicinal plants.
2011
Medicinal plants have been used as a source of remedies since ancient times in Egypt. The present study was designed to investigate the antibacterial activity and the cytotoxicity of the organic extracts from 16 selected medicinal plants of Egypt. The study was also extended to the isolation of the antiproliferative compound jaeschkeanadiol p-hydroxybenzoate (FH-25) from Ferula hermonis. The microbroth dilution was used to determine the minimal inhibitory concentration (MIC) of the samples against twelve bacterial strains belonging to four species, Providencia stuartii, Pseudomonas aeruginosa, Klebsiella pneumoniae, and Escherichia coli, while a resazurin assay was used to assess the cytoto…
Die Abwertung des Anderen mittels Sprache. Einflussfaktoren bei der Bewertung alltäglicher verbaler Gewalt im Amateurfußball
2020
International audience; The present study seeks to examine the underrepresented transnational phenomenon of everyday verbal abuse in amateur football. Based on 34 semi-structured interviews with German and French amateur referees, a contrastive sociolinguistic model was developed which allows to identify type-specific influencing factors on the evaluation of verbal abuse. Although individual referee related characteristics have similar values across different types, especially the high intrinsic motivation, active communication, the disturbing influence of third parties, and the identification of alleged perpetrator groups, the comparative analysis shows that personal ambition, knowledge of…
When more is less: The other side of artificial intelligence recommendation
2022
Based on consumers' preferences, AI (artificial intelligence) recommendation automatically filters information, which provokes scholars' debate. Supporters believe that by analyzing the consumers' preferences, AI recommendation enables consumers to choose products more quickly and with lower cost. Critics deem that consumers are more easily trapped in information cocoons because of the use of AI recommendation. This reduces the possibility of consumers contacting with a variety of commodities, thus lowering the consumer decision quality. Based on experiments, this paper discusses the moderating role of AI recommendation on the relationship of consumers' preferences and information cocoons. …
The Effects of General and Mobile Online Shopping Skilfulness and Multichannel Self-Efficacy on Consumer Showrooming Behaviour
2022
Although showrooming behaviour is a characteristic aspect of modern omnichannel retailing, our understanding of its antecedents remains limited. In this study, we aim to address this gap in prior research by examining how showrooming behaviour is affected by three different kinds of perceived consumer capabilities: general online shopping skilfulness, mobile online shopping skilfulness, and multichannel self-efficacy. The examination is done by utilising data from 1,024 Finnish consumers, which was collected with an online survey in 2021 and is analysed with structural equation modelling (SEM). In summary, we find mobile online shopping skilfulness to have a strong positive effect on showro…
Transforming an In-prior Conference into a Massive Online Event to Celebrate the United Nation's World Creativity and Innovation Day amidst the COVID…
2022
The University of Jyväskylä’s UNESCO Chairs and the Council for Creative Education-Finland decided to celebrate the United Nation’s World Creativity and Innovation Day in the form of a traditional, physical conference on 21 April 2020. During the last phases of preparations for the event, the COVID-19 pandemic unexpectedly hit the world and the organisers needed to transform the traditional conference program into an online event with several innovative solutions. In this chapter, the conference organisers describe the theoretical and technical background of the online conference, which has started a new conference series at the University of Jyväskylä. When it became clear that the confere…

The influence of red worm (E.Foetida) on compost's fertilizing properties
2014
Composting is becoming a more and more common way of biodegradable waste disposal. Composts should be characterized by high content of nutrients and low amount of pollutants. Vermicompost is a compost produced by overpopulated culture of earthworm Eisenia foetida (Savigny 1826). World scientific literature states that vermicompost has a high fertilizing value which often exceeds such value of conventional composts. The results showed that vermicompost has a much higher fertilizing value than the compost produced by the traditional pile method. However, prism vermicompost created with the participation of a less concentrated population of earthworms has an intermediate value as a fertilizer …
Vertex corrections for positive-definite spectral functions of simple metals
2016
We present a systematic study of vertex corrections in the homogeneous electron gas at metallic densities. The vertex diagrams are built using a recently proposed positive-definite diagrammatic expansion for the spectral function. The vertex function not only provides corrections to the well known plasmon and particle-hole scatterings, but also gives rise to new physical processes such as generation of two plasmon excitations or the decay of the one-particle state into a two-particles-one-hole state. By an efficient Monte Carlo momentum integration we are able to show that the additional scattering channels are responsible for the bandwidth reduction observed in photoemission experiments on…
