Assessment of ecotoxicity and total volatile organic compound (TVOC) emissions from food and children's toy products

2018

The development of new methods for identifying a broad spectrum of analytes, as well as highly selective tools to provide the most accurate information regarding the processes and relationships in the world, has been an area of interest for researchers for many years. The information obtained with these tools provides valuable data to complement existing knowledge but, above all, to identify and determine previously unknown hazards. Recently, attention has been paid to the migration of xenobiotics from the surfaces of various everyday objects and the resulting impacts on human health. Since children are among those most vulnerable to health consequences, one of the main subjects of interest…

Maladaptive Personality Traits and Their Interaction with Outcome Expectancies in Gaming Disorder and Internet-Related Disorders

2021

Gambling disorder and gaming disorder have recently been recognized as behavioral addictions in the ICD-11 (International Classification of Diseases, 11th edition). The association between behavioral addictions and personality has been examined before, yet there is a lack of studies on maladaptive traits and their relationship to specific outcome expectancies. In study 1, we recruited a community sample (n = 365)

Economic utopia of the Torah. Economic concepts of the Hebrew Bible interpreted according to the Rabbinical Literature

2004

Hebrew Bible offers alternative Economic utopia for building Theocratic society. In this paper, various economic concepts and themes are presented, as found in the Hebrew Bible. These economic concepts include taxation, property rights, labor market, social policy, banking, years of Sabbath and Jubilee, and business cycles. Most economic issues of the Bible are found in the texts of Torah, also known as five Books of Moses. These texts are analyzed by using classical Rabbinical commentaries for better insight. Contrary to the modern Economic theory which is based on the assumptions of scarcity of resources and unlimited needs of consumers, Economics of the Torah is based on God’s resources …

A comparative analysis of genetic variation in rootstocks and scions of old olive trees – a window into the history of olive cultivation practices an…

2014

Background Past clonal propagation of olive trees is intimately linked to grafting. However, evidence on grafting in ancient trees is scarce, and not much is known about the source of plant material used for rootstocks. Here, the Simple Sequence Repeat (SSR) marker technique was used to study genetic diversity of rootstocks and scions in ancient olive trees from the Levant and its implications for past cultivation of olives. Leaf samples were collected from tree canopies (scions) and shoots growing from the trunk base (suckers). A total of 310 trees were sampled in 32 groves and analyzed with 14 SSR markers. Results In 82.7% of the trees in which both scion and suckers could be genotyped, t…

Implications for dark matter direct detection in the presence of LIGO-motivated primordial black holes

2019

We discuss formation of dark matter (DM) mini-halos around primordial black holes (PBHs) and its implication on DM direct detection experiments, including axion searches. Motivated by LIGO observations, we consider $f_{\textrm{DM}} \simeq 0.01$ as the fraction of DM in PBHs with masses $10 M_{\odot} - 70 M_{\odot}$. In this case, we expect the presence of dressed PBHs after Milky Way halo formation with mini-halo masses peaked around $M_{\textrm{halo}} \sim (50-55) M_{\textrm{PBH}}$. We analyze the effect of tidal forces acting on dressed PBHs within the Milky Way galaxy. In the solar neighborhood, the mini-halos are resistant against tidal disruption from the mean-field potential of the ga…

Using Slack for computer-mediated communication to support higher education students’ peer interactions during Master’s thesis seminar

2018

Our study contributes to the research on computer-mediated communication in higher education by experimenting a modern communication tool called Slack. In particular, we consider using Slack to support students’ peer interactions during Master’s thesis work. For this purpose, we designed a case study that was executed in a Master’s thesis seminar course. During the course, all out-of-class communication was carried out by using Slack, instead of e-mails or learning management systems. After the course, we used a questionnaire to investigate how the students perceived Slack for asking for assistance, their intention to use Slack, and Slack’s ease of use. Furthermore, the questionnaire asked …

Pedagoģijas zinātnes ģenēze Latvijā no 20.gadsimta 20.gadiem līdz 60.gadu sākumam

2013

ANOTĀCIJA Ivetas Ozolas promocijas darba „Pedagoģijas zinātnes ģenēze Latvijā no 20. gadsimta 20. gadiem līdz 60. gadu sākumam” mērķis ir izpētīt, kā sociālpolitisku un zinātnes procesu kontekstā pedagoģija Latvijā laika posmā no 20. gadsimta 20. gadiem līdz 60. gadu sākumam veidojusies un attīstījusies kā patstāvīga zinātnes nozare. Darbā analizēti zinātnes veidošanās teorētiskie pamati, definējot dimensijas, kas raksturo atsevišķu zinātnes nozaru izveidošanos. Atbilstoši tām pētīta pedagoģijas zinātnes institucionālās, komunikatīvās un metodoloģiskās dimensijas attīstība Latvijā dažādu pedagoģijas paradigmu un sociālpolitisko apstākļu kontekstā. Pētījuma rezultāti apliecina, ka pedagoģija…

Co-evolution of three mega-trends nurtures un-captured GDP : Uber's ride-sharing revolution

2016

Uber used a disruptive business model driven by digital technology to trigger a ride-sharing revolution. The institution- al sources of the company’s platform ecosystem architecture were analyzed to explain this revolutionary change. Both an empirical analysis of a co-existing development trajectory with taxis and institutional enablers that helped to create Uber’s platform ecosystem were analyzed. The analysis identified a correspondence with the “two-faced” nature of ICT that nurtures uncaptured GDP. This two-faced nature of ICT can be attributed to a virtuous cycle of decline in prices and an increase in the number of trips. We show that this cycle can be attributed to a self-propagating…

Micropollutants removal in an anaerobic membrane bioreactor and in an aerobic conventional treatment plant

2012

The paper expresses an attempt to tackle the problem due to the presence of micropollutants in wastewater which may be able to disrupt the endocrine system of some organisms. These kinds of compounds are ubiquitously present in municipal wastewater treatment plant (WWTP) effluents. The aim of this paper is to compare the fate of the alkylphenols-APs (4-(tert-octyl)) phenol, t-nonylphenol and 4-p-nonylphenol and the hormones (estrone, 17ß-estradiol and 17¿-ethinylestradiol) in a submerged anaerobic membrane bioreactor (SAMBR) pilot plant and in a conventional activated sludge wastewater treatment plant (CTP). The obtained results are also compared with the results obtained in a previous stud…
