Krājumu pārvaldības metožu efektīva izmantošana SIA Rimi Latvia.

2015

Bakalaura darba tēma ir “Krājumu pārvaldības metožu efektīva izmantošana SIA Rimi Latvia” Tēma ir aktuāla gan ražojošam, gan tirdzniecības nozarē strādājošam uzņēmumam, jo krājumi ir pamats ražošanas un tirdzniecības nodrošināšanai. Pieejamā informācija parāda tikai dažas krājumu pārvaldības metodes, neapskatot to reālo pielietojumu strādājošā uzņēmumā. Līdz ar to ir nepieciešams noskaidrot, vai uzņēmējs savā darbībā ir izvēlējies pareizas krājumu pārvaldības metodes. Darba mērķis ir izpētīt SIA Rimi Latvia šobrīd pielietotās krājumu pārvaldības metodes, identificējot problēmas, ar kādām tās saskaras un izstrādāt priekšlikumus to pilnveidei. Darbs sastāv no četrām nodaļām. Pirmajā nodaļā ti…

How to Assess the Ecological Status of Highly Humic Lakes? Development of a New Method Based on Benthic Invertebrates

2021

Highly humic lakes are typical for the boreal zone. These unique ecosystems are characterised as relatively undisturbed habitats with brown water, high acidity, low nutrient content and lack of macrophytes. Current lake assessment methods are not appropriate for ecological assessment of highly humic lakes because of their unique properties and differing human pressures acting on these ecosystems. This study proposes a new approach suitable for the ecological status assessment of highly humic lakes impacted by hydrological modifications. Altogether, 52 macroinvertebrate samples from 15 raised bog lakes were used to develop the method. The studied lakes are located in the raised bogs at the c…

Effects of changing climate on European stream invertebrate communities : A long-term data analysis

2018

Long-term observations on riverine benthic invertebrate communities enable assessments of the potential impacts of global change on stream ecosystems. Besides increasing average temperatures, many studies predict greater temperature extremes and intense precipitation events as a consequence of climate change. In this study we examined long-term observation data (10-32years) of 26 streams and rivers from four ecoregions in the European Long-Term Ecological Research (LTER) network, to investigate invertebrate community responses to changing climatic conditions. We used functional trait and multi-taxonomic analyses and combined examinations of general long-term changes in communities with deta…

Seasonal and diel patterns of mayfly (Ephemeroptera) drift in Korge stream, Latvia

2009

A complex set of biotic and abiotic factors affects a drift. Mayfly drift has been extensively studied worldwide, but the manner in which the environmental factors interact is not completely clear. The aim of the present study was to characterise mayfly seasonal and diel drift patterns in relation to abiotic factors in a medium-sized lowland stream in Latvia. Drift samples were collected at three-hour intervals in a riffle section in May, August and September 2007. Distinct seasonal and diel patterns of the mayfly drift were observed in the Korge stream. These were not directly infuenced by primary hydraulic factors e.g. current velocity and discharge, but depended on the active growth peri…

Minimālās algas ietekme uz privātā sektora algu izkliedi Latvijā

2020

Maģistra darba tēma ir “Minimālās algas ietekme uz privātā sektora algu izkliedi Latvijā”. Tēma ir aktuāla, jo minimālā alga pēc darba autora domām ir bijusi un ir viens no strīdīgākajiem fiskālās politikas regulējošajiem instrumentiem, jo tad sastopas divas savstarpēji pretējas intereses – darba devēju un darba ņēmēju. Darba ņēmēji būs ieinteresēti saņemt pēc iespējams lielāku minimālo atalgojumu, tādējādi mazinot nabadzību un kompensējot inflāciju. Savukārt darba devēji vēlēsies maksāt pēc iespējas mazāku minimālo algu, lai samazinātu izmaksas, kuras saistītas ar mazkvalificēto darbinieku nodarbināšanu. Diskusijas, kuras ir saistītas ar minimālās algas izmaiņām būs aktuālas vienmēr, jo ga…
