Darba apjoms (bez pielikumiem) 77 lpp. Pirmajā nodaļā, balstoties uz literatūras analīzi, pamatota dabaszinību lielā loma pirmsskolā un izvērtētas dažādas dabaszinību mācīšanas tradīcijas. Otrajā nodaļā analizēts dabaszinību mācīšanas metodiskais darbs pirmsskolā. Trešā nodaļa veltīta veiktajam empīriskajam darbam – pedagogu aptaujas rezultātu analīzei. Nobeigumā…
Some critical remarks on the paper “A note on the metrizability of tvs-cone metric spaces” / Некоторые критические замечания о работе «Заметки о метр…
2018
This short and concise note provides a detailed exposition of the approach and results established by (Lin et al, 2015, pp.271-279). We show that the obtained results are not particularly surprising and new. Namely, using an old result due to K. Deimling it is indicated that tvs-cone metric spaces over solid cones are actually cone metric spaces over normal solid cones. Hence, there are only cone metric spaces over normal solid cones or over normal non-solid cones. One question still unanswered is whether an ordered topological vector space with a non-normal non-solid cone exists. / В представленных, в данной статье, заметках приведен подробный обзор методов и полученных результатов исследо…
Transitions in herd management of semi-domesticated reindeer in northern Finland. 45
2008
In northern Finland, reindeer-herd management has experienced two major transitions: extensification of intensive herding, and development of supplementary/corral feeding in winter. The transistions were studied in six herding associations in different parts of the Finnish reindeer management area. It was suggested that intensive herding turns into more extensive forms as the reasons for intensive herding (predation, reindeer disappearing to foreign areas, protection of agricultural fields) gradually ceased to exist. The results of the study, based on interviews of elderly reindeer herders, were variable. In the three southern areas intensive herding changed to the free ranging system at th…
Virszemes ūdeņu sastāva raksturojums meža meliorācijas sistēmās uz kūdras augsnēm: Kalsnavas piemērs
2020
Biogēno elementu palielinātās koncentrācijas ūdensobjektos ir galvenais eitrofikācijas cēlonis. Lielākoties tie ūdensobjektos nonāk no lauksaimniecības zemēm, taču meža teritorijas aizņem ~52 % no Latvijas teritorijas, tādēļ būtiski novērtēt to ietekmi uz virszemes ūdeņu sastāvu. Meža meliorācijas sistēmu (MMS) ierīkošana Latvijas apstākļiem atbilstošajos meža tipos būtiski uzlabo kokaudžu ražību, padarot to par neatņemamu mežsaimniecības sastāvdaļu, taču arī intensificē barības vielu izskalošanos. Potenciālo ietekmes novērtēšanai, bakalaura darbā raksturots ūdens sastāvs sešos ģeogrāfiski atdalītos MMS sateces baseinos uz kūdras augsnēm un saistītajā ūdenstilpē – Vesetas upē, kā arī aprēķi…
Does an intervention based on the pleasure of eating healthy foods could favour a positive relationship between food liking and perceived healthiness…
2019
International audience; It is generally admitted that consumers perceived unhealthy foods as tastier than healthy foods. However, the opposite association was found in French adults (Werle et al., 2013). Moreover, Marty et al. (2018) found that French children liked healthy foods as much as unhealthy foods. However, the link between liking and perceived healthiness in children needs to be further investigated, in particular at the individual level. Thus, our study aims, first at assessing the link between liking and perceived healthiness in children and, second at determining whether this potential link was modified after an intervention promoting pleasure of consuming healthy foods. To do …
How long-term mindfulness meditation practice affects the brain mechanisms of attention?
2015
In the last few decades, the beneficial effects of meditation and mindfulness have been broadly researched. Because attention plays a key role in mindfulness, it has been assumed that long-term practice of mindfulness meditation also has an impact on attention on neurophysiological level.In the current study, we explored how the long-term practice of mindfulness meditation affects the brain mechanisms of attention. We compared two groups, long-term meditation practisers and meditation novices. EEGscanning was conducted during an attention task of dichotic listening, where two stories were listened simultaneously, and participants were asked to concentrate in only one of the stories at a tim…

Bioloģiskā zīmējuma apguvi veicinošas metodikas izstrāde bioloģijas mācību stundās vidusskolas izglītības posmā
2021
BIOLOĢISKĀ ZĪMĒJUMA VEICINOŠAS METODIKAS IZSTRĀDE BIOLOĢIJAS MĀCĪBU STUNDAS VIDUSSKOLAS IZGLĪTĪBAS POSMĀ. J.Haļzovs, zinātniskā vadītāja vad. pētniece Dr.paed. Rita Birziņa. Maģistra darbs 143 lappuses, 3 attēli, 2 tabulas, 156 literatūras avoti, 26 pielikumi. Latviešu valodā. Bioloģiskais zīmējums bioloģijas mācību stundu īstenošanā tiek pielietots kā viena no mācību metodēm dažādu bioloģisko objektu pētīšanai pamatskolā un vidusskolā. Lai attīstītu skolēnu prasmi veidot bioloģisko zīmējumu, nepieciešams noteikt galvenās kļūdas, kuras saistītas ar bioloģiskā zīmējuma veidošanu, izveidot ieteikumus skolotājiem darbā ar optiskās palielināšanas ierīcēm un piedāvāt ieteikumus metodoloģiskajam …
How amniotic fluid shapes early odor-guided responses to colostrum and milk (and more)
2016
Revue; Among the multiple transitions that characterize mammalian development, birth certainly is the most abrupt and spectacular. It is also the most challenging for newborns when one considers their high mortality rates in any mammalian species. Although evolution has selected newborn organisms that possess the physiological and behavioral keys leading to adapt to this harsh psychobiological challenge, their capabilities cannot be considered separately from the maternal organism and the environment she creates. Mammalian females provide indeed passive (physiological) and/or active (behavioral) assistance to complement and boost their offspring’s capacities. One notable strategy of mammali…
Mindfulness-acceptance-commitment program for athletes and exercisers : an action research case study
2016
Control-based psychological skills training (PST) practices have been widely capitalized on in sport for the past few decades, despite inconsistent empirical evidence of their efficacy on sport performance. The Mindfulness-Acceptance-Commitment (MAC) program has preliminary support as an additional approach in performance enhancement, however, there is very limited research involving its implementation especially within group settings. Current study was aimed at planning, implementation, and evaluation of a seven-session MAC program among a diverse group of active athletes and regular exercisers (n=16). This study was an educational action research case study with a mixed method design. Per…
