Korejiešu popa latviešu fanu identitātes veidošanās
2022
Bakalaura darba “Korejiešu popa latviešu fanu identitātes veidošanās” ietvaros mērķis ir noskaidrot izpētīt kā korejiešu popa fani Latvijā veido savu sociālo identitāti un vai un kā korejiešu popa fanu subkultūra un dalība tajā ietekmē identitātes veidošanos. Pētījuma ietvaros izmantota sociālās identitātes un subkultūru teorija. Izmantojot kvalitatīvo datu ieguves metodi - daļēji strukturētās intervijas - tika noskaidrotas četru fanu pieredzes un tas, kā korejiešu popa fani Latvijā identificējas ar korejiešu popa fanu subkultūru un kā dalība subkultūrā ietekmēja viņu identitātes veidošanos. Galvenie secinājumi ir, ka korejiešu popa fani Latvijā izjūt piederību korejiešu popa fanu subkultūr…
The trophic transfer of persistent pollutants (HCB, DDTs, PCBs) within polar marine food webs.
2017
Biomagnification (increase in contaminant concentrations at successively higher levels of trophic web), is a process that can transversally impair biodiversity and human health. Most research shows that biomagnification should be higher at poles with northern sites having a major tendency to biomagnify Persistent Organic Pollutants (POPs) through their marine food webs. We investigated the biomagnification degree into two marine trophic webs combining carbon and nitrogen stable isotopes and POP analyses. We showed that the Antarctic trophic web was more depleted than the sub-Arctic one and the differences highlighted for the basal part could explain the difference in length between them. Co…
Individual variation of persistent organic pollutants in relation to stable isotope ratios, sex, reproductive phase and oxidative status in Scopoli's…

Abstract: Little is known about the accumulation of persistent organic pollutants (POPs) and its consequences for seabirds in the Mediterranean basin. We characterised the plasma contaminant profile (polychlorinated biphenyls ΣPCBs; organochlorine pesticides ΣOCPs; polybrominated diphenyl ethers ΣPBDEs) of a population of the seabird Scopoli's shearwater (Calonectris diomedea) that breeds in the southern Mediterranean (Linosa Island) and investigated (i) whether sex, stable isotope ratios (related to diet), reproductive phase (early incubation vs. late breeding season) and body mass explained variation in contaminant burden and (ii) whether they predict health-related variables. The predomi…
